Noctilucent Clouds Over Germany
Credit & Copyright: Christoph Rollwagen
Explanation: Sometimes it's night on the ground but day in the air. As the Earth rotates to eclipse the Sun, sunset (http://antwrp.gsfc.nasa.gov/apod/ap070713.html) rises up from the ground. Therefore, at sunset on the ground, sunlight still shines on clouds (http://ww2010.atmos.uiuc.edu/%28Gh%29/guides/mtr/cld/home.rxml) above. Under usual circumstances, a pretty sunset (http://antwrp.gsfc.nasa.gov/apod/ap980526.html) might be visible, but unusual noctilucent clouds (http://en.wikipedia.org/wiki/Noctilucent_clouds) float so high up they can be seen well after dark. Pictured above last week, a network of noctilucent clouds (http://www.youtube.com/watch?v=pslcQXWQz3k) cast an eerie white glow after dusk, beyond a local field near Potsdam (http://en.wikipedia.org/wiki/Potsdam), Germany (http://en.wikipedia.org/wiki/Germany). Although noctilucent clouds (http://www.spaceweather.com/nlcs/gallery2009_page1.htm) are thought to be composed of small ice-coated particles, much remains unknown (http://www.nlcnet.co.uk/) about them. Satellites launched to help study these clouds includes Sweden's Odin (http://en.wikipedia.org/wiki/Odin_%28satellite%29) and NASA's AIM (http://en.wikipedia.org/wiki/Aeronomy_of_Ice_in_the_Mesosphere). Recent evidence (http://www.nrl.navy.mil/pressRelease.php?Y=2003&R=35-03r) indicates that at least some noctilucent clouds (http://www.youtube.com/watch?v=-xF2vSKINK0) result from freezing water exhaust from Space Shuttle (http://antwrp.gsfc.nasa.gov/apod/ap021023.html)s.

Greenland by Air



This photo of the Sondrestrom Glacier in Greenland was taken from a window on NASA's Gulfstream III environmental research aircraft as it flew along the Fjord outside of Kangerlussuaq on June 4. The synthetic aperture radar mounted on the aircraft's belly had just completed the repeat pass of southeast Greenland and was on its way back to Thule Air Base during the Arctic Ice Radar Mission.

Jack Hills, Australia

The oldest material on Earth which has yet been dated by man is a zircon mineral that is 4.4 billion years old and comes from a sedimentary gneiss in the Jack Hills of Australia's Narre Gneiss Terrane. It is the most ancient fragment of the earth’s crust so far identified, formed approximately 150 million years after the planet itself. In August 2007, scientists reported finding the world’s oldest diamond crystals, encased inside the zircon crystals.

The image was acquired by ASTER on Oct. 12, 2004. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of about 50 to 300 feet, ASTER images Earth to map and monitor the changing surface of our planet and is one of five Earth-observing instruments launched Dec. 18, 1999, on NASA's Terra satellite.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change.

Shedding Light on Dark Gamma Ray Bursts

Gamma-ray bursts are the universe's biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. Yet, for more than a decade, astronomers have puzzled over the nature of so-called dark bursts, which produce gamma rays and X-rays but little or no visible light. They make up roughly half of the bursts detected by NASA's Swift satellite since its 2004 launch.

Using one of the world's largest optical telescopes, the Keck I in Hawaii, researchers looked for unknown galaxies at the locations of 14 Swift-discovered dark bursts.

In this artist's concept, dense knots of dust in otherwise normal galaxies dim the light of a dark gamma-ray burst (center). The dust absorbs most or all of a burst's visible light but not higher-energy X-rays and gamma rays.

Molecular Cloud Barnard 68
Credit: FORS Team (http://www.eso.org/instruments/fors1/), 8.2-meter VLT Antu (http://www.eso.org/projects/vlt/), ESO (http://www.eso.org/)
Explanation: Where did all the stars go? What used to be considered a hole in the sky is now known to astronomers as a dark molecular cloud (http://en.wikipedia.org/wiki/Molecular_cloud). Here, a high concentration of dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html) and molecular gas (http://antwrp.gsfc.nasa.gov/apod/ap970430.html) absorb practically all the visible light emitted from background stars. The eerily dark surroundings help make the interiors of molecular clouds (http://www.youtube.com/watch?v=YbdwTwB8jtc) some of the coldest and most isolated places in the universe. One of the most notable of these dark absorption nebulae (http://antwrp.gsfc.nasa.gov/apod/dark_nebulae.html) is a cloud toward the constellation Ophiuchus (http://www.seds.org/Maps/Stars_en/Fig/ophiuchus.html) known as Barnard 68 (http://en.wikipedia.org/wiki/Barnard_68), pictured above (http://www.eso.org/gallery/v/ESOPIA/Stars/phot-02a-01.tif.html). That no stars are visible in the center indicates that Barnard (http://en.wikipedia.org/wiki/Edward_Emerson_Barnard) 68 is relatively nearby, with measurements placing it about 500 light-years away and half a light-year (http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html) across. It is not known exactly how molecular clouds (http://archive.ncsa.uiuc.edu/Cyberia/Bima/GMC.html) like Barnard 68 (http://curious.astro.cornell.edu/question.php?number=597) form, but it is known that these clouds are themselves likely places (http://antwrp.gsfc.nasa.gov/apod/ap070218.html) for new stars to form (http://zebu.uoregon.edu/%7Ejs/ast122/lectures/lec14.html). In fact, Barnard 68 (http://adsabs.harvard.edu/abs/2009ApJ...695.1308B) itself has recently been found (http://www.universetoday.com/2009/06/09/astronomers-predict-birth-of-a-new-star/) likely to collapse and form a new star system. It is possible to look right through (http://www.eso.org/outreach/press-rel/pr-1999/phot-29-99.html) the cloud in infrared (http://coolcosmos.ipac.caltech.edu/cosmic_classroom/ir_tutorial/discovery.html) light.

Seaside Moon Mirage
Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Jean-Marc Audrin (%20audrin%20at%20sympatico%20dot%20ca) Explanation: This surprising view of the Full Moon rising on (http://stardate.org/nightsky/moon/) June 7 was captured with a telephoto lens from a seaside balcony near Nice, France. The orange Moon's (http://antwrp.gsfc.nasa.gov/apod/ap050922.html) dark markings and odd shape put the photographer in mind of an alien creature's face staring down at the passing ship. Of course, the Moon's distorted appearance is due to the unusual bending (refraction (http://interactagram.com/physics/optics/refraction/)) of light rays creating multiple images or mirages (http://en.wikipedia.org/wiki/Mirage_of_astronomical_objects), similar to sunset and sunrise mirages (http://www.atoptics.co.uk/atoptics/sunmir.htm). The effects are most pronounced when temperature layers (http://www.atoptics.co.uk/atoptics/mirtemp.htm) in the atmosphere produce sharp changes in air density and refractive index. Acting over long sight-lines to the rising and setting Sun or Moon, the refraction significantly alters the path of light rays (http://www.atoptics.co.uk/atoptics/gfmmform.htm) creating merged, distorted images. Such mirages are also associated with the Green Flash (http://antwrp.gsfc.nasa.gov/apod/ap040321.html).

Sunrise over the Parthenon
Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Anthony Ayiomamitis (http://www.perseus.gr/) (TWAN (http://www.twanight.org/)) Explanation: Today, the sun will stay in the sky longer than any other day of the year, as seen from the northern hemisphere of Earth. Named the Summer Solstice, today's maximum daylight (http://antwrp.gsfc.nasa.gov/apod/ap080922.html) is indicative of the high amount of sunlight this time of year that is primarily responsible for the heat of the summer season (http://en.wikipedia.org/wiki/Summer). At the north pole (http://antwrp.gsfc.nasa.gov/apod/ap040919.html) and for all places above the arctic circle (http://en.wikipedia.org/wiki/Arctic_Circle), there will be no night -- the entire day today will be lit by sunlight. The situation is reversed in Earth's southern hemisphere, where today has the least sunlight of any day. Today's solstice (http://en.wikipedia.org/wiki/Solstice) is commemorated above by a well-planned picture (http://www.perseus.gr/Astro-Solar-Scenes-Parthenon-04.htm) of our five billion year old Sun rising behind the 2,500 year old Parthenon (http://en.wikipedia.org/wiki/Parthenon) in Greece (http://en.wikipedia.org/wiki/Greece). Trees and birds occupy the foreground, while a modern crane (http://cic.nist.gov/vrml/equip.html) is shown restoring parts of this historic symbol of a cultural civilization (http://www.historyworld.net/wrldhis/PlainTextHistories.asp?historyid=ab25).

Stars at the Galactic Center
Credit: Susan Stolovy (SSC/Caltech (http://ssc.spitzer.caltech.edu/)) et al. (http://www.spitzer.caltech.edu/Media/releases/ssc2006-02/moreinfo.shtml), JPL-Caltech (http://www.jpl.nasa.gov/), NASA (http://www.nasa.gov/) Explanation: The center (http://antwrp.gsfc.nasa.gov/apod/ap040411.html) of our Milky Way Galaxy is hidden (http://antwrp.gsfc.nasa.gov/apod/ap051004.html) from the prying eyes of optical telescopes by clouds of obscuring dust and gas. But in this stunning vista (http://www.spitzer.caltech.edu/Media/releases/ssc2006-02/ssc2006-02a.shtml), the Spitzer Space Telescope's infrared (http://coolcosmos.ipac.caltech.edu/cosmic_classroom/ir_tutorial/importance.html) cameras, penetrate much of the dust revealing (http://www.youtube.com/watch?v=Z_SOytjGxlM) the stars of the crowded galactic center (http://en.wikipedia.org/wiki/Galactic_center) region. A mosaic of many smaller snapshots, the detailed, false-color image shows (http://www.spitzer.caltech.edu/Media/releases/ssc2006-02/release.shtml) older, cool stars in bluish hues. Reddish glowing dust clouds are associated with young, hot stars in stellar nurseries. The very center of the Milky Way was only recently found capable (http://www.spitzer.caltech.edu/Media/releases/ssc2009-13/release.shtml) of forming newborn stars (http://www.universetoday.com/2009/06/10/astronomers-announce-first-newborn-stars-at-milky-ways-core/). The galactic center (http://antwrp.gsfc.nasa.gov/apod/ap051023.html) lies some 26,000 light-years away, toward the constellation Sagittarius (http://hawastsoc.org/deepsky/sgr/index.html). At that distance, this picture spans about 900 light-years.

The Milky Road
Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Larry Landolfi (http://db2.photoresearchers.com/search?function=query&key=BN1636) Explanation: Inspired by the night skies of planet Earth in the International Year of Astronomy (http://www.iya2009.org/), photographer Larry Landolfi created this tantalizing fantasy (http://www.landolfiphoto.com/Site_2/SURREAL_FUN_.html) view. The composited image (http://www.landolfiphoto.com/Site_2/-Composited_Astrophotos-.html) suggests a luminous Milky Way is the heavenly extension of a country road. Of course, the name (http://en.wikipedia.org/wiki/List_of_names_for_the_Milky_Way) for our galaxy, the Milky Way (http://seds.org/messier/more/mw.html) (in Latin, Via Lactea), does refer to its appearance as a milky band or path in the sky. In fact, the word galaxy itself derives from the Greek for milk. Visible on moonless nights (http://antwrp.gsfc.nasa.gov/apod/ap040923.html) from dark sky (http://antwrp.gsfc.nasa.gov/apod/ap070508.html) areas, though not so bright or colorful as in this image, the glowing celestial band (http://science.nasa.gov/headlines/y2001/ast01nov_1.htm) is due to the collective light of myriad stars along the plane of our galaxy, too faint to be distinguished individually. The diffuse starlight is cut by dark swaths of obscuring galactic dust clouds. Four hundred years ago, Galileo turned his telescope on the Milky Way and announced it to be "... a congeries of innumerable stars (http://www.100hoursofastronomy.org/component/content/article/55-rfienberg/230-qoh-my-god-its-full-of-starsq) ..."

Stereo Image: Patrick Vantuyne (http://www.tridi.be/) Explanation: From 400 kilometers above planet Earth (http://spaceflight.nasa.gov/realdata/tracking/index.html), the Expedition 20 Crew onboard the International Space Station (ISS (http://antwrp.gsfc.nasa.gov/apod/ap090406.html)) was able to witness a remarkable event from a remarkable vantage point -- the June 12 eruption of the Sarychev Peak Volcano (http://www.volcano.si.edu/world/volcano.cfm?vnum=0900-24=). The active volcano is located in Russia's Kuril Island chain (http://en.wikipedia.org/wiki/Kuril_Islands), stretching to the northeast of Japan. Emphasizing the orbital perspective, this stunning color stereo view (http://www.tridi.be/) was made by combining two images from the ISS (http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=38985) and is intended to be viewed with red/blue glasses (http://mpfwww.jpl.nasa.gov/MPF/mpf/glasses.html) (red for the left eye). Punching upwards into the atmosphere at an early stage of the eruption, the volcanic plume features a brown column of ash topped with a smooth, bubble-like, white cloud that is likely water condensation. Below, a cloud of denser grey ash slides down the volcanic slope. About 1.5 kilometers of the island coastline is visible at ground level. The evolving ash plume (http://earthobservatory.nasa.gov/NaturalHazards/event.php?id=38937) posed no danger to the Expedition 20 crew, but commercial airline flights were diverted away from the region to minimize the danger of engine failures from ash intake

Triton

The Voyager 2 spacecraft took this color photo of Neptune's moon Triton on Aug. 24 1989, at a range of 330,000 miles. The image was made from pictures taken through the green, violet and ultraviolet filters. In this technique, regions that are highly reflective in the ultraviolet appear blue in color. In reality, there is no part of Triton that would appear blue to the eye. The bright southern hemisphere of Triton, which fills most of this frame, is generally pink in tone, as is the even brighter equatorial band. The darker regions north of the equator also tend to be pink or reddish in color.

Solstice to Solstice Solargraph
Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Maciej Zapiór (http://www.asu.cas.cz/%7Esos/staff/maciek/zapior.htm) Explanation: This six month long exposure compresses the time (http://www.moma.org/collection/browse_results.php?object_id=79018) from solstice to solstice (~ December 21, 2008 to June 20, 2009) into a single point of view. Dubbed a solargraph, the unconventional picture (http://www.asu.cas.cz/%7Esos/staff/maciek/puszki.htm) was recorded with a pinhole camera made from (http://www.pinholephotography.org/Solargraph%20instructions.htm) an aluminum can lined with a piece of photographic paper. Fixed to a single spot (http://www.solargraphy.com/index.php?option=com_content&task=view&id=16&Itemid=18) for the entire exposure, the simple camera continuously records the Sun's daily path as a glowing trail burned into the photosensitive paper. Breaks and gaps in the trails are caused by cloud cover. In this case, the spot was chosen to look out from inside a radio telescope (http://www.asu.cas.cz/_data/k40l_1232294978.jpg) at the Ondrejov Observatory (http://www.asu.cas.cz/history) in the Czech Republic. At the end of the exposure, the paper was removed from the can and immediately scanned digitally. Contrasts and colors were then enhanced and added to the digital image. Of course, in December, the Sun trails begin lower (http://antwrp.gsfc.nasa.gov/apod/ap071222.html) down at the northern hemisphere's winter solstice. The trails climb higher (http://antwrp.gsfc.nasa.gov/apod/ap081221.html) in the sky as the June 21st summer solstice approaches.

The magnificent view (http://antwrp.gsfc.nasa.gov/apod/image/0906/Tassili_tafreshi.jpg) was recorded from Tassili National Park (http://whc.unesco.org/en/list/179), in the heart of the Sahara desert in southern Algeria. Rising above eroded sandstone cliffs (http://www.dreamview.net/dv/new/photos.asp?id=101903&cat=Nature), the celestial menagerie of constellations includes Draco (http://www.windows.ucar.edu/tour/link=/mythology/draco_dragon.html&edu=high) the Dragon, Cygnus (http://www.windows.ucar.edu/tour/link=/mythology/cygnus.html&edu=high) the Swan, Aquila (http://www.windows.ucar.edu/tour/link=/the_universe/Constellations/summer/aquila.html&edu=high) the Eagle, and Scorpius (http://www.windows.ucar.edu/tour/link=/mythology/scorpius.html) the Scorpion. Ruling planet Jupiter shines through clouds very close to the horizon near picture center, while star clouds of the Milky Way arc through Sagittarius (http://antwrp.gsfc.nasa.gov/apod/ap070711.html) above the rocks at the far right. Bright blue stars Deneb (http://antwrp.gsfc.nasa.gov/apod/ap070920.html), in Cygnus, and Altair (http://www.astro.illinois.edu/%7Ejkaler/sow/altair.html), in Aquila, also shine in the starry night along with Scorpius' bright yellowish star Antares (http://antwrp.gsfc.nasa.gov/apod/ap080603.html), the rival of Mars. Prehistoric skygazers surely witnessed a similar sky. In addition to dramatic sandstone formations, the Tassili region (http://en.wikipedia.org/wiki/Tassili_n%27Ajjer) is noted for rock art (http://www.metmuseum.org/toah/hd/tass/hd_tass.htm) and archaeological sites dating to Neolithic times (http://en.wikipedia.org/wiki/Neolithic) when the local climate was wetter

ازاي قدروا يسرحزا بخيالهم و يقولوا دول شبه الميزان ودول شبه العقرب
غريبة


فعلا غريبة .. ولكن اعتقد أنهم أطلقوا عليها هذه الأسماء للمقاربة و ذلك لتسهيل الحفظ و التذكر، لا لإستطاعتهم رؤية تلك الصور و التشكيلات بهذا الوضوح .. ومع ذلك فإن جو الصحراء الخالية، وإتساع السماء السمردي يحتمان بل يجبران الخيال على الإنطلاق و التحليق.

و حقيقية انا لم أستطع أن أشعر بمعنى اَيتي الليل و النهار حتى خرجت إلى الصحراء و إستقررت بها .. ولهذا نحن مأمرون بالسير في الأرض و النظر .. وبغير ذلك لن نستطيع إدراك أيات الله في خلقه. ولذلك أغبط بشدة علماء الطبيعة و الاحياء و التاريخ الطبيعي و الأحياء البحرية و الجيلوجيين و علماء الفلك و حتى الرحالة و المستكشفيين العاديين الذين يتمتعون بمزية الصعود لاعالي الجبال و سبر أعماق البحار و التحليق في السماء و طي سطح الأرض إستنفاذا لحياتهم تأملا و تفاعلا فيزيائيا و روحيا مع كل عناصر هذا الكون.

Fresh Tiger Stripes on Saturn's Enceladus
Credit: Cassini Imaging Team (http://ciclops.org/), SSI (http://www.spacescience.org/), JPL (http://www.jpl.nasa.gov/), ESA (http://www.esa.int/), NASA (http://www.nasa.gov/) Explanation: Do underground oceans vent through the tiger stripes on Saturn's moon Enceladus? Long features dubbed tiger stripes are known to be spewing ice (http://antwrp.gsfc.nasa.gov/apod/ap071013.html) from the moon's icy interior into space, creating a cloud of fine ice particles over the moon's South Pole and creating Saturn's mysterious E-ring (http://antwrp.gsfc.nasa.gov/apod/ap070327.html). Evidence for this has come from the robot Cassini spacecraft (http://saturn.jpl.nasa.gov/mission/presentposition/) now orbiting Saturn (http://en.wikipedia.org/wiki/Saturn). Pictured above (http://photojournal.jpl.nasa.gov/catalog/PIA06254), a high resolution image of Enceladus is shown from a close flyby. The unusual surface features dubbed tiger (http://en.wikipedia.org/wiki/Tiger) stripes are visible on in false-color blue. Why Enceladus (http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search?enceladus) is active remains a mystery, as the neighboring moon Mimas (http://antwrp.gsfc.nasa.gov/apod/ap090517.html), approximately the same size, appears quite dead (http://www.davidpbrown.co.uk/jokes/monty-python-parrot.html). Most recently, an analysis of dust (http://saturn.jpl.nasa.gov/news/newsreleases/newsrelease20090624/) captured by Cassini found evidence (http://www.youtube.com/watch?v=0BzXC4qfV44) for sodium as expected in a deep salty ocean. Conversely however, recent Earth-based observations of ice ejected by Enceladus into Saturn's E-Ring showed no evidence (http://www.universetoday.com/2009/06/24/does-enceladus-harbor-a-liquid-ocean-reasonable-minds-disagree/) of the expected sodium (http://en.wikipedia.org/wiki/Sodium). Such research is particularly interesting since such an ocean would be a candidate to contain life (http://www1.nasa.gov/mission_pages/cassini/media/enceladus-f20080326.html).

3-2-1 and Liftoff of GOES-O

Rising above the pad's fixed service tower, a Delta IV rocket soars into the sky with the GOES-O satellite aboard. Liftoff was at 6:51 p.m. EDT from Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The first attempt to launch GOES-O, on June 26, was scrubbed due to thunderstorms. The latest Geostationary Operational Environmental Satellite, GOES-O was developed by NASA for the National Oceanic and Atmospheric Administration, or NOAA. Each of the GOES satellites continuously provides observations of 60 percent of the Earth including the continental United States, providing weather monitoring and forecast operations as well as a continuous and reliable stream of environmental information and severe weather warnings. Once in orbit, GOES-O will be designated GOES-14, and NASA will provide on-orbit checkout and then transfer operational responsibility to NOAA.

The North America and Pelican Nebulae
Credit & Copyright: Danny Lee Russell (%20stargazzzer%20at%20prodigy%20dot%20net) Explanation: Here are some familiar shapes in unfamiliar locations. This emission nebula (http://antwrp.gsfc.nasa.gov/apod/emission_nebulae.html) on the left is famous partly because it resembles Earth's continent of North America (http://en.wikipedia.org/wiki/North_America). To the right of the North America Nebula (http://en.wikipedia.org/wiki/North_America_Nebula), cataloged as NGC 7000, is a less luminous nebula that resembles a pelican (http://en.wikipedia.org/wiki/Pelican) dubbed the Pelican Nebula (http://antwrp.gsfc.nasa.gov/apod/ap020829.html). The two emission nebula (http://en.wikipedia.org/wiki/Nebula) measure about 50 light-years across, are located about 1,500 light-years (http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html) away, and are separated by a dark absorption (http://antwrp.gsfc.nasa.gov/apod/dark_nebulae.html) cloud. This spectacular image captures the nebulas, bright ionization fronts (http://antwrp.gsfc.nasa.gov/apod/ap000703.html), and fine details of the dark dust. The nebulae can be seen (http://www.youtube.com/watch?v=LtKUuAM3zDY) with binoculars from a dark location. Look for a small nebular patch (http://antwrp.gsfc.nasa.gov/apod/ap971009.html) north-east of bright star Deneb (http://www.astro.wisc.edu/%7Edolan/constellations/hr/7924.html) in the constellation of Cygnus (http://www.astro.wisc.edu/%7Edolan/constellations/constellations/Cygnus.html). It is still unknown which star or stars ionize the red-glowing hydrogen (http://periodic.lanl.gov/elements/1.html) gas.

ببساطة لأننا ما عندناش قاعدة صواريخ فضائية .. او بالمعني الروسي "مطار فضائي" و غالبا المطارات الفضائية كانت مطارات حربية أو قواعد صواريخ بعيدة المدى ... أنا شفت فيلم وئائقي مزهل على قناة روسيا اليوم عن المطار الفضائي الروسي ... و شفت كيف ان تصنيع صاروخ , تجريبه و تامينه عسكريا و نقله وإطلاقه و تاريخ الحوادث التي حدثت ، لهي أمور عظيمة جدا و مكلفة جدا جدا جدا ... ولكن بالطبع الامم ذات الهمم العالية لا يستعصيها أمر .. بالصدفة سمعت المسلماني في برنامج الطبعة الاولى بيتكلم عن القمر المصري للأبحاث ( EgyptSat1 ) إللي تم إطلاقه عام 2007 .. (ولا عمري كنت سمعت عنه الصراحة) .. و كان بيقول إن ( Egypt Sat 2 ) سيتم تصنيعه كاملا في مصر و بخبرة مصرية و سيتم إطلاقه خلال العام أو العامين القادمين ... بالطبع نحن نطمح للمزيد .. ولكن لو حدث هذا فسيكون خطوة هامة على الدرب

Three Galaxies in Draco
Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Giovanni Benintende (http://www.astrogb.com/) Explanation: This intriguing trio of galaxies is sometimes called the Draco Group, located in the northern constellation of (you guessed it) Draco (http://www.hawastsoc.org/deepsky/dra/index.html). From left to right are edge-on spiral (http://antwrp.gsfc.nasa.gov/apod/ap010510.html) NGC 5981, elliptical galaxy (http://antwrp.gsfc.nasa.gov/apod/ap060520.html) NGC 5982, and face-on spiral (http://antwrp.gsfc.nasa.gov/apod/ap040410.html) NGC 5985 -- all within this single telescopic field of view spanning a little more than half the width of the full moon. While the group is far too small to be a galaxy cluster (http://www.seds.org/messier/gal_clus.html) and has not been cataloged (http://www.astro.ubc.ca/people/hickson/hcg/) compact group, these galaxies all do lie roughly 100 million light-years from planet Earth. On close examination with spectrographs (http://imagine.gsfc.nasa.gov/docs/science/how_l1/spectral.html), the bright core of the striking face-on spiral NGC 5985 shows prominent emission in specific wavelengths of light, prompting astronomers to classify it as a Seyfert (http://www.seds.org/%7Espider/spider/ScholarX/seyferts.html), a type of active galaxy. Not as well known as other tight groupings of galaxies (http://antwrp.gsfc.nasa.gov/apod/ap090313.html), the contrast in visual appearance makes this triplet an attractive subject for astrophotographers. This impressively deep exposure (http://www.astrogb.com/ngc5982.htm) of the region also reveals faint and even more distant background galaxies (http://www.noao.edu/outreach/aop/observers/bggalaxies.html).

A Super-Efficient Particle Accelerator

This image, created from data obtained from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope, shows a part of the roughly circular supernova remnant known as RCW 86. This remnant of an exploded star may be the one observed in 185 AD by Chinese astronomers. By studying it, astronomers gained a better understanding of new details about the role of supernova remnants as the Milky Way's super-efficient particle accelerators.

Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Anthony Ayiomamitis (http://www.perseus.gr/) (TWAN (http://www.twanight.org/)) Explanation: Today, the sun will stay in the sky longer than any other day of the year, as seen from the northern hemisphere of Earth. Named the Summer Solstice, today's maximum daylight (http://antwrp.gsfc.nasa.gov/apod/ap080922.html) is indicative of the high amount of sunlight this time of year that is primarily responsible for the heat of the summer season (http://en.wikipedia.org/wiki/Summer). At the north pole (http://antwrp.gsfc.nasa.gov/apod/ap040919.html) and for all places above the arctic circle (http://en.wikipedia.org/wiki/Arctic_Circle), there will be no night -- the entire day today will be lit by sunlight. The situation is reversed in Earth's southern hemisphere, where today has the least sunlight of any day. Today's solstice (http://en.wikipedia.org/wiki/Solstice) is commemorated above by a well-planned picture (http://www.perseus.gr/Astro-Solar-Scenes-Parthenon-04.htm) of our five billion year old Sun rising behind the 2,500 year old Parthenon (http://en.wikipedia.org/wiki/Parthenon) in Greece (http://en.wikipedia.org/wiki/Greece). Trees and birds occupy the foreground, while a modern crane (http://cic.nist.gov/vrml/equip.html) is shown restoring parts of this historic symbol of a cultural civilization (http://www.historyworld.net/wrldhis/PlainTextHistories.asp?historyid=ab25).

Illustration: NASA/CXC/M.Weiss (http://chandra.harvard.edu/photo/2009/labs/) Explanation: Dubbed a Lyman-alpha blob, an enormous cloud of hydrogen gas spans several hundred thousand light-years in this remarkable image (http://chandra.harvard.edu/photo/2009/labs/) (left), a composite of x-ray, optical, and infrared (http://coolcosmos.ipac.caltech.edu/cosmic_classroom/multiwavelength_astronomy/multiwavelength_astronomy/) data from space and ground based observatories. The gigantic, amoeba-like structure is seen as it was when the universe was (http://antwrp.gsfc.nasa.gov/apod/ap060323.html) a mere (http://www.astro.ucla.edu/%7Ewright/CosmoCalc.html) 2 billion years old (about 12 billion years ago (http://map.gsfc.nasa.gov/universe/uni_age.html)). Lyman-alpha blobs are so called because they strongly emit radiation due to the Lyman-alpha emission (http://en.wikipedia.org/wiki/Lyman_series) line of hydrogen gas. Normally, Lyman-alpha emission is in the ultraviolet part of the spectrum, but Lyman-apha blobs are so distant, their light is redshifted to (longer) optical wavelengths (http://hyperphysics.phy-astr.gsu.edu/hbase/ems1.html). X-ray data (blue) indicates (http://arxiv.org/abs/0904.0452) the presence of a supermassive black hole (http://chandra.harvard.edu/xray_sources/blackholes_sm.html) feeding at the center of an active galaxy embedded in the blob. Illustrated close up in the right hand panel, radiation and outflows from the active galaxy are thought to be a source for energizing and heating the blob's hydrogen gas. In fact, Lyman-alpha blobs could represent an early phase in galaxy formation where the heating is so great it begins to limit further rapid growth of active galaxies (http://chandra.harvard.edu/xray_sources/quasars.html) and their supermassive black holes.

Perihelion and Aphelion
Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Enrique Luque Cervigón (http://www.ascensionrecta.com/) Explanation: This year Aphelion, the point in Earth's elliptical orbit (http://www.windows.ucar.edu/tour/link=/physical_science/physics/mechanics/orbit/ellipse.html&edu=high) when it is farthest from the Sun, occurs tomorrow, July 4th. Of course, that doesn't affect the seasons (http://csep10.phys.utk.edu/astr161/lect/time/seasons.html) on our fair planet (http://eol.jsc.nasa.gov/). Those are determined by the tilt of Earth's axis of rotation and not Earth's distance from the Sun, so July is still winter in the south and summer in northern hemisphere. But it does mean that on July 4th the Sun will be at its smallest apparent size. This composite neatly compares two pictures of the Sun taken with the same telescope and camera on the dates of (http://aa.usno.navy.mil/data/docs/EarthSeasons.php) Perihelion (closest approach) and Aphelion in 2008. The image labels include Earth's distance in kilometers from the Sun on the two dates. Otherwise difficult to notice (http://www.sungazer.net/), the change in the Sun's apparent diameter between Perihelion and Aphelion (http://www.windows.ucar.edu/tour/link=/physical_science/physics/mechanics/orbit/perihelion_aphelion.html&edu=high) is clear. The difference amounts to a little over 3 percent

The Moon and stars of Taurus (with the Pleiades) and Perseus accompany the spectacular view of Comet Hale-Bopp above the Great Pyramids of Giza in 1997, probably more than four thousand years since the comet’s last appearance. Comet Hale-Bopp’s intriguing connection to our ancient past inspired the photographer to document the comet above two of the most famous ancient monuments in the world, the Pyramids of Giza, (Egypt) and Stonehenge (England). A fascinating journey followed, successfully documenting this unique and unrepeatable event. As noted by the photographer "Watching the comet above the Pyramids prompted my curiosity. Did ancient people see the comet? How have ancient cultures been influenced by astronomical events? What can we learn from this for today? It is a privilege to have documented a great comet appearing above world heritage sites, and an experience I’ll always remember". John Goldsmith

Genesis Mission's Hard Impact

Credit: Genesis Mission (http://genesismission.jpl.nasa.gov/), NASA (http://www.nasa.gov/) Explanation: A flying saucer from outer space crash-landed in the Utah desert in 2004 after being tracked by radar and chased by helicopters. No space aliens (http://www.daviddarling.info/encyclopedia/S/SFafter1940.html) were involved, however. The saucer, pictured above (http://www.nasa.gov/mission_pages/genesis/multimedia/genesisrecov090804-2.html), was the Genesis sample return capsule, part of a human-made robot Genesis spaceship (http://www.jpl.nasa.gov/news/features.cfm?feature=635) launched in 2001 by NASA itself to study the Sun. The unexpectedly hard landing (http://www.youtube.com/watch?v=U2H-UkMBZ68) at over 300 kilometers per hour occurred because the parachutes did not open as planned. The Genesis mission (http://en.wikipedia.org/wiki/Genesis_%28spacecraft%29) had been orbiting the Sun (http://www.nineplanets.org/sol.html) collecting solar wind (http://antwrp.gsfc.nasa.gov/apod/ap970217.html) particles that are usually deflected away by Earth's magnetic field (http://csep10.phys.utk.edu/astr161/lect/earth/magnetic.html). Despite the crash landing, many return samples remained in good enough condition to analyze and research is ongoing (http://adsabs.harvard.edu/abs/2009LPI....40.1373B). So far, discoveries include new details about the composition (http://genesismission.jpl.nasa.gov/gm2/news/features/closer.htm) of the Sun (http://antwrp.gsfc.nasa.gov/apod/ap070624.html) and the effects of the solar wind on unprotected material (http://adsabs.harvard.edu/abs/2009NIMPB.267.1101C).

Many cultures from around the world have been inspired and influenced by the celestial. The crescent moon adorning the minaret towers provide an example of astronomical symbolism in the islamic religion. John goldsmith.

Unknown Dark Material on Mercury

Credit: MESSENGER (http://messenger.jhuapl.edu/who_we_are/teams.html), NASA (http://www.nasa.gov/), JHU APL (http://www.jhuapl.edu/), CIW (http://www.ciw.edu/) Explanation: What is that strange material on Mercury? When flying by Mercury (http://www.youtube.com/watch?v=hq4rA9vYKBw) last October, the robotic MESSENGER spacecraft (http://en.wikipedia.org/wiki/MESSENGER) imaged much of the solar system's innermost planet (http://en.wikipedia.org/wiki/Mercury_%28planet%29) in unprecedented detail. As common in science, new data bring new mysteries. Pictured above (http://photojournal.jpl.nasa.gov/catalog/PIA11389) on the lower right, a large crater -- about 100 kilometers across -- has unusual dark material of unknown composition near its center. The material's darkness does not appear to be caused by shadow (http://antwrp.gsfc.nasa.gov/apod/ap070610.html)s, as the Sun was near zenith (http://en.wikipedia.org/wiki/Zenith) when the image was taken. One origin hypothesis is that the dark material (http://antwrp.gsfc.nasa.gov/apod/ap090118.html) was uncovered from beneath Mercury's surface during the impact that created the surrounding crater. If so, the composition of the dark mound might be similar to the composition of some mysterious (http://photojournal.jpl.nasa.gov/catalog/PIA11357) dark ring (http://photojournal.jpl.nasa.gov/catalog/PIA11763)s also recently discovered on Mercury. Alternatively, the dark material could be related to an unusual composition of the impacting rock (http://antwrp.gsfc.nasa.gov/apod/ap090328.html). MESSENGER will buzz past (http://www.youtube.com/watch?v=7bESWV_oKqI) Mercury again later this year before entering orbit in 2011.

Northern lights in a moonlit evening on Cleary Summit, about 30 km north of Fairbanks, Alaska. As noted by the photographer "The aurora just before this shot was taken was directly overhead. But then the arc started to collapse, and the aurora oval pulled away and began shrinking off to the north. You could see that the current display was shutting down for the evening, and I knew the oval would soon pull back to the northern horizon where I was now facing. The arc was rapidly growing smaller and smaller, so I knew I was now getting the last of the shots of the ending part of that evenings show. The aurora was not about to turn around and start to rebuild, it was in the phase of winding down. It had reached the point of no return, and it was time to say goodbye for the evening. One last look while it was still high in the sky, even though it was at least 200 miles away by now. It was getting near time to go back home anyway, as it was about 3:00am, and I was once again ready for the warmth of bed and sleep." LeRoy Zimmerman/Photosymphony.com

The Milky Way fades in the morning light as seen from the Assekrem Mountain in central African Sahara or southern Algeria near to tropic of Cancer. Click on the black star-lines icon above the image to recognize the planets and constellation figures. The Assekrem peak, as the main proposed site for Algerian National Observatory, is one of the highest in Hoggar Mountains with an exceptional overview to many giant volcanic cliffs which raised from the desert. Assekrem, means "the End of the World" in the old Saharan Taureg language, is known as one of the most scenic area of Sahara but it is also famous as the point where the priest le Père de Foucauld lived in the summer of 1905 and there are still several European priests who are living here in the middle of Sahara. Notable in the sky of this early morning panorama: At left planets Mars and Venus meets in constellation Pisces above the raising morning light. Continue the line of Mars and Venus upward and you will find the dazzling Jupiter high in the sky above south. The line simply shows the ecliptic or plane of the Solar System as seen in our sky. Look below Jupiter to find bright star Fomalhaut or the Alpha (brightest) star of Piscis Austrinus. To its below left is the southern constellations Grus. Pan more to the right to see the orange light glow toward south west from the oasis town of Tamanrasset some 80km away. More to the right is the central budge of the Milky Way in the constellations Scorpius and Sagittarius while setting in the west.

Cassini--The Mission Continues

As Saturn advanced in its orbit toward equinox and the sun gradually moved northward on the planet, the motion of Saturn's ring shadows and the changing colors of its atmosphere continued to transform the face of Saturn as seen by Cassini in this image from the mission's fourth year.

Cassini has been orbiting Saturn for five Earth years as of June 30, 2009. That's about one sixth of a Saturnian year, enough time for the spacecraft to have observed seasonal changes in the planet, its moons and sunlight's angle on the dramatic rings.

This captivating natural color view was created from images collected shortly after Cassini began its extended Equinox Mission in July 2008. The mosaic combines 30 images--10 each of red, green and blue light—taken over the course of approximately two hours as Cassini panned its wide-angle camera across the entire planet and ring system on July 23, 2008, from a southerly elevation of 6 degrees.

Six moons complete this constructed panorama (see the full-size image): Titan (3,200 miles, or 5,150 kilometers, across), Janus (111 miles, or 179 kilometers, across), Mimas (396 kilometers, or 246 miles, across), Pandora (81 kilometers, or 50 miles, across), Epimetheus (70 miles, or 113 kilometers, across) and Enceladus (504 kilometers, or 313 miles, across).

Cassini captured these images at a distance of approximately 690,000 miles (1.1 million kilometers) from Saturn and at a sun-Saturn-spacecraft, or phase, angle of 20 degrees.

The Trifid Nebula in Stars and Dust

Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Adam Block (http://www.caelumobservatory.com/index.html), Mt. Lemmon SkyCenter (http://skycenter.arizona.edu/), U. Arizona (http://www.as.arizona.edu/)

Explanation: Unspeakable beauty and unimaginable bedlam can be found together in the Trifid Nebula (http://www.seds.org/messier/m/m020.html). Also known as M20, this photogenic nebula (http://skycenter.arizona.edu/m20.html) is visible (http://antwrp.gsfc.nasa.gov/apod/ap011229.html) with good binoculars towards the constellation (http://www.astro.wisc.edu/%7Edolan/constellations/extra/constellations.html) of Sagittarius (http://www.astro.wisc.edu/%7Edolan/constellations/constellations/Sagittarius.html). The energetic processes of star formation (http://antwrp.gsfc.nasa.gov/apod/ap030816.html) create not only the colors but the chaos (http://en.wikipedia.org/wiki/Chaos_%28physics%29). The red-glowing gas (http://antwrp.gsfc.nasa.gov/apod/ap980828.html) results from high-energy starlight striking interstellar hydrogen (http://periodic.lanl.gov/elements/1.html) gas. The dark dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html) filaments (http://antwrp.gsfc.nasa.gov/apod/ap010928.html) that lace M20 (http://antwrp.gsfc.nasa.gov/apod/ap970828.html) were created in the atmospheres of cool giant stars (http://www.astro.keele.ac.uk/workx/starlife/StarpageS_26M.html) and in the debris (http://antwrp.gsfc.nasa.gov/apod/ap990803.html) from supernovae (http://imagine.gsfc.nasa.gov/docs/science/know_l1/supernovae.html) explosions. Which bright young stars light up the blue reflection nebula (http://antwrp.gsfc.nasa.gov/apod/reflection_nebulae.html) is still being investigated (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1986AJ.....92.1125L). The light from M20 (http://en.wikipedia.org/wiki/Trifid_Nebula) we see today left perhaps 3,000 years ago, although the exact distance remains unknown. Light takes about 50 years to cross M20 (http://www.youtube.com/watch?v=aolbM62bfNA).

This composite image depicts the moon's rugged south polar region and is the the highest resolution topography map to date of the moon's south pole. It was generated by scientists at NASA's Jet Propulsion Laboratory, using data collected using the Deep Space Network's Goldstone Solar System Radar located in California's Mojave Desert. This new map provides contiguous topographic detail over a region approximately 311 miles by 249 miles (500 kilometers by 400 kilometers).

The Dark River to Antares

Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Jason Jennings (http://cosmicphotos.com/)

Explanation: Connecting the Pipe Nebula (http://antwrp.gsfc.nasa.gov/apod/ap090522.html) to the colorful regon near bright star Antares is a dark cloud dubbed the Dark River (http://www.astropix.com/HTML/D_SUM_S/PIPE.HTM), flowing from the picture's left edge. Murky looking, the Dark River (http://antwrp.gsfc.nasa.gov/apod/ap030928.html)'s appearance is caused by dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html) obscuring background starlight, although the dark nebula contains mostly hydrogen (http://periodic.lanl.gov/elements/1.html) and molecular gas. Surrounded by dust, Antares (http://www.astro.uiuc.edu/%7Ekaler/sow/antares.html), a red supergiant star, creates an unusual bright yellowish reflection nebula. Above it, bright blue double star Rho Ophiuchi (http://www.astro.illinois.edu/%7Ejkaler/sow/rhooph.html) is embedded in one of the more typical bluish reflection (http://antwrp.gsfc.nasa.gov/apod/ap090521.html) nebulae, while red emission (http://antwrp.gsfc.nasa.gov/apod/ap080424.html) nebulae are also scattered around the region. Globular star cluster M4 (http://antwrp.gsfc.nasa.gov/apod/ap000523.html) is just seen above and right of Antares, though it lies far behind the colorful clouds, at a distance of some 7,000 light-years. The Dark River itself is about 500 light years (http://chandra.harvard.edu/photo/cosmic_distance.html) away. The colorful skyscape (http://cosmicphotos.com/gallery/image.php?fld_image_id=181&fld_album_id=9) is a mosaic of telescopic images spanning nearly 10 degrees (20 Full Moons) across the sky in the constellation Scorpius.

MLAS Launches

NASA successfully demonstrated an alternate system for future astronauts. The launch of the Max Launch Abort System, or MLAS, took place on July 8, 2009, at 6:26 a.m. at NASA's Wallops Flight Facility, Wallops Island, Va.

The unpiloted launch tested an alternate concept for safely propelling a future spacecraft and its crew away from a problem on the launch pad or during ascent. The MLAS consists of four solid rocket abort motors inside a bullet-shaped composite fairing attached to a full-scale mockup of the crew module.

The 33-foot-high MLAS vehicle was launched to an altitude of approximately one mile to simulate an emergency on the launch pad. The flight demonstration began after the four solid rocket motors burned out. The crew module mockup separated from the launch vehicle at approximately seven seconds into the flight and parachuted into the Atlantic Ocean.

In this long exposure image from top of La Palma in Canary Islands, lights from nearby villages and small towns are dramatically scattered due to the dust from Sahara. As noted by the photographer "The bright lights are from the small town of Barlovento at sea level. The dust from the desert was quite severe at that time and its effect was to prevent the normal temperature drop during the night so that the usual cloud layer closer to sea level did not form, allowing street lights at sea level to be reflected by the airborne dust. On the south side if the island, the mainly fluorescent street lights of Tazacorte and Los Llanos to the south provided the color contrast in this image."David Malin/Davidmalin.com

Stephan's Quintet--A Galaxy Collision in Action

Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth, provides a rare opportunity to observe a galaxy group in the process of evolving from an X-ray faint system dominated by spiral galaxies to a more developed system dominated by elliptical galaxies and bright X-ray emission. Being able to witness the dramatic effect of collisions in causing this evolution is important for increasing our understanding of the origins of the hot, X-ray bright halos of gas in groups of galaxies.

The Pillars of Eagle Castle

Credit & Copyright: Emanuele Colognato (http://www.backyardskies.com/BackyardSkies/About_Me.html) & Jim Wood (Backyard Skies (http://www.backyardskies.com/))

Explanation: What lights up this castle (http://en.wikipedia.org/wiki/Castle) of star formation? The familiar Eagle Nebula (http://antwrp.gsfc.nasa.gov/apod/ap090208.html) glows bright in many colors at once. The above image (http://www.backyardskies.com/BackyardSkies/M16_Information.html) is a composite of three of these glowing gas colors. Pillars of dark dust (http://antwrp.gsfc.nasa.gov/apod/ap070218.html) nicely outline some of the denser tower (http://en.wikipedia.org/wiki/Tower)s of star formation (http://en.wikipedia.org/wiki/Star_formation). Energetic light from young massive stars causes the gas to glow and effectively boils (http://www.youtube.com/watch?v=kieGBkOdyMU) away part of the dust (http://antwrp.gsfc.nasa.gov/apod/ap961119.html) and gas from its birth pillar. Many of these stars will explode (http://www.youtube.com/watch?v=RgfbjHz_UTo) after several million years, returning most of their elements back to the nebula which formed them. This process is forming an open cluster (http://antwrp.gsfc.nasa.gov/apod/ap960903.html) of stars known as M16 (http://seds.lpl.arizona.edu/messier/m/m016.html).

Hybrid Wing Body Model

NASA's Glenn Research Center dedicated a model of the hybrid wing body, a futuristic aircraft concept, on July 8, 2009. The center is testing parts of a new propulsion system that can be embedded in the wing of the airplane. Developed by NASA and Boeing, the plane is called a hybrid wing body because its wings and fuselage blend together in a triangular shape. The concept could revolutionize air travel because of its potential to increase fuel efficiency, while reducing noise and emissions.

Noctilucent Cloud Storm Panorama

P-M Hedén (Clear Skies (http://www.clearskies.se/), TWAN (http://www.twanight.org/))

Explanation: Noctilucent or night-shining clouds lie near the edge of space (http://earthobservatory.nasa.gov/IOTD/view.php?id=7953). From about 80 kilometers above Earth's surface, the icy clouds (http://www.nasa.gov/mission_pages/aim/index.html) can still reflect sunlight even though the Sun itself is below the horizon as seen from the ground (http://spaceweather.com/nlcs/gallery2009_page6.htm). Usually occurring at high latitudes in summer months, the diaphonous apparitions are also known as polar mesospheric clouds (http://antwrp.gsfc.nasa.gov/apod/astropix.html) and may be connected to global change (http://climate.jpl.nasa.gov/) in the lower atmosphere. This impressive 360 degree panorama made from 34 separate images captures an impressive display of noctilucent clouds all over the sky. It was recorded last month from Vallentuna, Sweden. The photographer reports that the display was like a noctilucent cloud storm, one of the best he's ever witnessed (http://antwrp.gsfc.nasa.gov/apod/ap060718.html).

Comet Hyakutake passed very close to Earth in March of 2006, less than two months after its discovery. It dubbed The Great Comet of 1996; its passage near the Earth was one of the closest cometary approaches of the previous 200 years. As recorded here from Dunkirk, Maryland, at the East Coast of US, Hyakutake appeared very bright in the night sky with its tail lengths of up to 80 degrees in dark skies. Fred Espenak/Mreclipse.com

Telescopes of the VERITAS (Very Energetic Radiation Imaging Telescope Array System) gamma-ray observatory are photographed against the stars of constellation Leo. Located on the Mount Graham of Arizona, in the Whipple Observatory, The array consists of four 12m optical reflectors for gamma-ray astronomy. Since the cosmic gamma-rays are blocked by the atmosphere, astrononers detect either by space telescope and through detection of secondary particles and radiation caused by their interaction with the atmosphere. The VERITAS telescopes detect Cherenkov radiation to study the gamma-rays. When high-energy particles or strong cosmic gamma-rays interacts with the Earth's atmosphere, it may produce electron-positron pairs with enormous velocities. Cherenkov radiation is a very faint light created when charged particles (such as an electron) passes through a medium like the atmosphere at a constant speed greater than the speed of light in that medium. The Cherenkov radiation from these charged particles is used to determine the source and intensity of the original cosmic radiation. P.K. Chen

Erupting Volcano Anak Krakatau

Credit & Copyright (http://www.swisseduc.ch/stromboli/about/copyright-en.html): Marco Fulle (http://www.ts.astro.it/astro/gente2.html) (Stromboli Online)


Explanation: A volcano on Krakatoa (http://en.wikipedia.org/wiki/Krakatoa) is still erupting. Perhaps most famous for the powerfully explosive eruption (http://www.geology.sdsu.edu/how_volcanoes_work/Krakatau.html) in 1883 that killed tens of thousands of people, ash from a violent eruption (http://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa) might also have temporarily altered Earth's climate as long as 1500 years ago. In 1927, eruptions caused smaller Anak Krakatau (http://en.wikipedia.org/wiki/Krakatoa#Anak_Krakatau) to rise from the sea, and the emerging volcanic island continues to grow at an average rate of 2 cm per day. The latest eruption (http://www.youtube.com/watch?v=q8yuk8KUzjQ) of Anak Krakatau started in 2008 April and continues today. In this picture (http://www.swisseduc.ch/stromboli/perm/krakatau/krakatau-storm-stars-en.html), Anak Krakatau is seen erupting from Rakata (http://www.britannica.com/EBchecked/topic/323164/Krakatoa), the main island of the Krakatoai group. High above, stars including the Big Dipper (http://antwrp.gsfc.nasa.gov/apod/ap070108.html) are clearly apparent.

Explanation: Earth's Moon and planet Jupiter (http://antwrp.gsfc.nasa.gov/apod/ap081106.html) made a beautiful pairing in the night sky late last week. This skyscape (http://www.astrosurf.com/ubb/Forum3/HTML/022397.html) recorded on July 11 from Brittany in north western France captures the bright conjunction through a cloud bank. The clouds add drama (http://antwrp.gsfc.nasa.gov/apod/ap090430.html) and mystery (http://antwrp.gsfc.nasa.gov/apod/ap080411.html) to the scene but they were also positioned to reduce the intense moonlight. As a result, the exposure captures Jupiter's own Galilean moons (http://www2.jpl.nasa.gov/galileo/ganymede/discovery.html) (lower right) as tiny pinpricks of light, lined up and hugging both sides of the solar system's ruling gas giant (http://antwrp.gsfc.nasa.gov/apod/ap001118.html). Later this week, the Moon (http://www.skyandtelescope.com/observing/ataglance) is headed for a conjunction with Mars and Venus in the dawn sky.

Saturn I Booster Tests



A Saturn I booster model is set up for testing in NASA Lewis (now Glenn) Research Center's Supersonic Wind Tunnel in 1960. The model had eight working rocket engines with 250 pounds of thrust each. The tests simulated actual flight conditions, providing valuable information to optimize vehicle stability and air pressure distribution.

The Saturn I had a cluster of eight rocket nozzles in the first stage and was used to lift Apollo into low Earth orbit to test out the spacecraft and to later support the Skylab and Apollo-Soyuz Test project.

Explanation: The Chameleon is a small constellation near the south celestial pole (http://antwrp.gsfc.nasa.gov/apod/ap061202.html). Boasting no bright stars (http://hawastsoc.org/deepsky/cha/), it blends inconspicuously with the starry southern sky. But, taken in dark skies over Namibia, this image reveals a stunning aspect of the shy constellation -- a field of dusty nebulae and colorful stars. Blue reflection (http://antwrp.gsfc.nasa.gov/apod/ap090610.html) nebulae are scattered through the scene, but most eye-catching is the complex of silvery dust clouds that only faintly reflect starlight, punctuated by dense dark nebulae (http://antwrp.gsfc.nasa.gov/apod/ap090425.html). The dark nebulae stand out because they block out background stars. This view of the cosmic dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html) clouds spans about 4 degrees on the sky.

Endeavour Lifts Off

Under a cloud-washed sky, spectators watch as space shuttle Endeavour rises majestically from Launch Pad 39A at NASA's Kennedy Space Center in Florida on the STS-127 mission to the International Space Station. Liftoff was at 6:03 p.m. EDT on July 15, 2009, and was the sixth launch attempt for the mission. The launch was scrubbed on June 13 and June 17 when a hydrogen gas leak occurred during tanking due to a misaligned ground umbilical carrier plate. The mission was postponed July 11, 12 and 13 due to weather conditions near the Shuttle Landing Facility at Kennedy that violated rules for launching, and lightning issues.

Endeavour will deliver the Japanese Experiment Module's Exposed Facility and the Experiment Logistics Module-Exposed Section in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the station.

The Hercules Cluster of Galaxies

Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Tony Hallas (http://astrophoto.com/contact.htm)

Explanation: These are galaxies of the Hercules Cluster (http://www.astr.ua.edu/gifimages/hercules.html), an archipelago of island universes (http://antwrp.gsfc.nasa.gov/apod/ap051222.html) a mere 500 million light-years away (http://www.faqs.org/faqs/astronomy/faq/part8/section-14.html). Also known as Abell 2151, this cluster (http://www.atlasoftheuniverse.com/superc/her.html) is loaded with gas and dust rich, star-forming spiral (http://antwrp.gsfc.nasa.gov/apod/ap070529.html) galaxies but has relatively few elliptical (http://antwrp.gsfc.nasa.gov/apod/ap060520.html) galaxies, which lack gas and dust and the associated newborn stars. The colors in this remarkably deep composite (http://www.qsimaging.com/gallery.html) image clearly show the star forming galaxies with a blue tint and galaxies with older stellar populations with a yellowish cast. The sharp picture spans about 3/4 degree across the cluster center, corresponding to over 6 million light-years at the cluster's estimated distance. In the cosmic vista many galaxies seem to be colliding (http://antwrp.gsfc.nasa.gov/apod/ap040612.html) or merging (http://antwrp.gsfc.nasa.gov/apod/ap090618.html) while others seem distorted (http://antwrp.gsfc.nasa.gov/apod/ap030607.html) - clear evidence that cluster galaxies (http://www.seds.org/messier/gal_clus.html) commonly interact. In fact, the Hercules Cluster itself may be seen as the result of ongoing mergers of smaller galaxy clusters and is thought to be similar to young (http://antwrp.gsfc.nasa.gov/apod/ap040226.html) galaxy clusters in the much more distant, early Universe (http://antwrp.gsfc.nasa.gov/apod/ap060323.html).

Starburst Galaxy M94

Credit & Copyright (http://antwrp.gsfc.nasa.gov/apod/lib/about_apod.html#srapply): Marcin Paciorek (podzamcze23%20at%20gmail%20dot%20com)

Explanation: Beautiful island universe M94 lies (http://www.seds.org/messier/m/m094.html) a mere 15 million light-years distant in the northern constellation of the hunting dogs, Canes Venatici (http://en.wikipedia.org/wiki/Canes_Venatici). A popular target for earth-based astronomers (http://astroexpo.pl/), the face-on spiral galaxy (http://coolcosmos.ipac.caltech.edu/cosmic_classroom/multiwavelength_astronomy/multiwavelength_museum/m94.html) is about 30,000 light-years across. Its remarkable features include prominent dust lanes, a bright, point-like nucleus, and a bright, bluish ring dominated by the light of young, massive stars. The massive stars in the ring are all likely less than 10 million years old, indicating the galaxy experienced a well-defined era of rapid star formation. As a result, while the small, bright nucleus is typical of the Seyfert (http://seds.org/%7Espider/spider/scholarx/seyferts.html) class of active galaxies, M94 is also known as a starburst galaxy (http://chandra.harvard.edu/xray_sources/starburst.html). Because M94 is relatively nearby, astronomers can explore in detail (http://arxiv.org/abs/astro-ph/0011101) reasons for the galaxy's burst of star formation.

Adjacent to the Kennedy Space Center thousands of spectators camped out on beaches and roads to watch the launch of Apollo 11, which launched at 9:32 a.m. Eastern on July 16, 1969.

The launch of Apollo 11 was the culmination of 8 years of hard work by thousands of scientists and technicians. Four days later, Apollo 11 commander Neil Armstrong stepped out of the lunar module and took "one small step" in the Sea of Tranquility, calling it "a giant leap for mankind."

Explanation: This dramatic skyscape was recorded during the August 2008 (http://antwrp.gsfc.nasa.gov/apod/ap080821.html) total solar eclipse. The Moon's silhouette surrounded by a glistening solar corona hangs above the Jiayuguan Fort along the western edge of the Great Wall (http://www.nasa.gov/vision/space/workinginspace/great_wall.html) of China. Lined-up along the ecliptic (http://antwrp.gsfc.nasa.gov/apod/ap040501.html) plane, all the planets of the inner solar system, Mercury, Venus, Mars, (and Earth!) can also be seen along with Saturn and (http://antwrp.gsfc.nasa.gov/apod/ap070309.html) bright star Regulus, as the Moon's shadow tracks (http://antwrp.gsfc.nasa.gov/apod/ap070610.html) across the landscape. Beyond the Moon's shadow, outside the total eclipse track, sunlight still brightens the sky over mountains on the horizon 30 - 50 kilometers away. Much anticipated (http://www.skyandtelescope.com/observing/highlights/50020537.html), the 2009 July 22nd total solar eclipse (http://eclipse.gsfc.nasa.gov/SEmono/TSE2009/TSE2009.html) will again be visible from China. Planets and bright stars will briefly appear in darkened daytime skies (http://antwrp.gsfc.nasa.gov/apod/ap080920.html), though a total eclipse won't be seen from the Great Wall. Still, major cities and populated areas lie along the 2009 total eclipse track (http://eclipse.gsfc.nasa.gov/SEmono/TSE2009/TSE2009fig/TSE2009globe1a.JPG) that begins in India and sweeps eastward across Asia and into the Pacific Ocean.

Explanation: One of the most identifiable nebulae in the sky, the Horsehead Nebula (http://en.wikipedia.org/wiki/Horsehead_Nebula) in Orion (http://www.astro.wisc.edu/%7Edolan/constellations/constellations/Orion.html), is part of a large, dark, molecular cloud (http://antwrp.gsfc.nasa.gov/apod/ap090623.html). Also known as Barnard (http://en.wikipedia.org/wiki/Edward_Emerson_Barnard) 33, the unusual shape was first discovered (http://www.seds.org/messier/xtra/ngc/b33.html) on a photographic plate (http://www.astro.virginia.edu/%7Eafs5z/photography.html) in the late 1800s. The red glow originates from hydrogen (http://periodic.lanl.gov/elements/1.html) gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis (http://www.dibonsmith.com/ori_s.htm). The darkness of the Horsehead (http://antwrp.gsfc.nasa.gov/apod/ap061015.html) is caused mostly by thick dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html), although the lower part of the Horsehead (http://antwrp.gsfc.nasa.gov/apod/ap081126.html)'s neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field (http://www-spof.gsfc.nasa.gov/Education/whmfield.html). Bright spots in the Horsehead Nebula (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1987AJ.....93.1514Z)'s base are young stars just in the process of forming (http://antwrp.gsfc.nasa.gov/apod/ap070218.html). Light takes about 1,500 years to reach us from the Horsehead Nebula (http://antwrp.gsfc.nasa.gov/apod/ap090224.html). The above image (http://www.noao.edu/image_gallery/html/im0057.html) was taken with the 0.9-meter telescope (http://www.noao.edu/0.9m/index.html) at Kitt Peak National Observatory (http://www.noao.edu/kpno/kpno.html).

Have you ever seen a halo around the Sun or the Moon? This fairly common sight occurs when high thin clouds containing millions of tiny ice crystals cover much of the sky. Each ice crystal acts like a miniature lens. Because most of the crystals have a similar elongated hexagonal shape, light entering one crystal face and exiting through the opposing face refracts 22 degrees, which corresponds to the radius of the Sun or the Moon Halo.

Only two days before the 2008 summer solstice, which marks the northernmost point of the Sun's annual motion through our sky, the Full Moon nearest the solstice rose close to the ecliptic plane opposite the Sun, near its southernmost point for the year. In this telephoto view the Moon rises above the first modern Television Tower of Stuttgart, built in 1956. As described by the photographer "Not by accident, but by approximation, I suspected the Moon would rise near the old television tower from my photography location, Gruener Heiner, a very small mountain (only 70 meters high) in Weilimdorf, near Stuttgart. The Moon crossed the horizon line somewhat more in the north, but it moved exactly above the tower. It was the beginning of the very shortest full Moon night of the year, because of the very low declination of the Moon. I had even more luck, because the haze at the horizon made the Moon shining in red and yellow light. As well, the Moonlight was dimmed, so I could manage a landscape shot in the dark. Even then I had to make an exposure bracketing: a series of five images with different exposure times to handle the huge dynamic of the scene. I combined the five images with different exposures to one High Dynamic Image (HDI). Usually some romantic people are walking to the top of the hill where I photographed. They come to watch the Sunset. I told them to stay because of the upcoming Moonrise. Those who stayed were more than happy for such celestial experience!” Stefan Seip/Astromeeting.de.

The Lagoon Nebula in Gas, Dust, and Stars

Credit & Copyright: Florencio Rodil (http://florencior.fotoastronomia.net/index.html)

Explanation: Stars are battling gas and dust in the Lagoon Nebula but the photographers are winning. Also known as M8, this photogenic nebula (http://florencior.fotoastronomia.net/imagenes/preferidas/m8_HaSHO+ha_50.jpg) is visible (http://antwrp.gsfc.nasa.gov/apod/ap011229.html) even without binoculars towards the constellation (http://www.astro.wisc.edu/%7Edolan/constellations/extra/constellations.html) of Sagittarius (http://www.astro.wisc.edu/%7Edolan/constellations/constellations/Sagittarius.html). The energetic processes of star formation (http://antwrp.gsfc.nasa.gov/apod/ap030816.html) create not only the colors but the chaos (http://antwrp.gsfc.nasa.gov/apod/ap031228.html). The red-glowing gas (http://antwrp.gsfc.nasa.gov/apod/emission_nebulae.html), shown on the above left in re-assigned colors (http://astroprofspage.com/archives/1500), results from high-energy starlight striking interstellar hydrogen (http://en.wikipedia.org/wiki/Hydrogen) gas. The Trifid nebula (http://antwrp.gsfc.nasa.gov/apod/ap090707.html) is visible on the far right. The dark dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html) filaments (http://antwrp.gsfc.nasa.gov/apod/ap010928.html) that lace M8 (http://www.seds.org/messier/m/m008.html) were created in the atmospheres of cool giant stars (http://www.astro.keele.ac.uk/workx/starlife/StarpageS_26M.html) and in the debris (http://antwrp.gsfc.nasa.gov/apod/ap990803.html) from supernovae (http://imagine.gsfc.nasa.gov/docs/science/know_l1/supernovae.html) explosions. The light from M8 we see today left about 5,000 years ago (http://en.wikipedia.org/wiki/3rd_millennium_BC). Light takes about 50 years to cross this section of M8 (http://antwrp.gsfc.nasa.gov/apod/ap090519.html).

Work Continues on the Station

In this one of a series of digital still images, astronaut Dave Wolf performs his second spacewalk, which is also the second of five scheduled spacewalks for the STS-127 mission. Astronauts Wolf and Tom Marshburn (out of frame) successfully transferred a spare KU-band antenna to long-term storage on the space station, along with a backup coolant system pump module and a spare drive motor for the station's robot arm transporter. Installation of a television camera on the Japanese Exposed Facility experiment platform was deferred to a later spacewalk.

The Big Corona

Credit & Copyright: Koen van Gorp (http://users.skynet.be/vangorp/)

Explanation: Most photographs don't adequately portray the magnificence of the Sun (http://www.nineplanets.org/sol.html)'s corona. Seeing the corona (http://www.lmsal.com/YPOP/Spotlight/Tour/corona2.html) first-hand during a total solar eclipse (http://en.wikipedia.org/wiki/Total_solar_eclipse) is best. The human eye (http://iknow.net/phys_eye_education.html) can adapt to see features and extent that photographic film (http://web.islandnet.com/%7Eyesmag/how_work/film.html) usually cannot. Welcome, however, to the digital (http://antwrp.gsfc.nasa.gov/apod/ap060620.html) age. The above picture (http://www.koenvangorp.be/events/eclipse_2006.html) is a combination of thirty-three photographs that were digitally processed to highlight faint features of a total eclipse that occurred in March of 2006. The images of the Sun's corona (http://www.windows.umich.edu/cgi-bin/tour.cgi?link=/sun/atmosphere/corona.html) were digitally altered to enhance dim, outlying waves and filaments. Shadow seekers (http://sunearth.gsfc.nasa.gov/eclipse/eclipse.html) need not fret, though, since as yet there is no way that digital image processing can mimic the fun (http://antwrp.gsfc.nasa.gov/apod/ap990902.html) involved in experiencing (http://www.exploratorium.edu/eclipse/personal_accounts.html) a total solar eclipse. Last week (http://antwrp.gsfc.nasa.gov/apod/ap090724.html), a spectacular total solar eclipse occurred (http://www.youtube.com/watch?v=M_lXu9hPPg8) over southern Asia, while the The next total solar eclipse (http://eclipse.gsfc.nasa.gov/SEmono/TSE2009/TSE2009fig/TSE2009globe1a.JPG) will be visible from (http://eclipse.gsfc.nasa.gov/SEmono/TSE2010/TSE2010.html) the South Pacific (http://en.wikipedia.org/wiki/South_Pacific_%28musical%29) on 2010 July 11.

NGC 1097: Spiral Galaxy with a Central Eye
Credit: NASA (http://www.nasa.gov/), JPL-Caltech (http://www.spitzer.caltech.edu/), SINGS Team (http://sings.stsci.edu/) (SSC (http://ssc.spitzer.caltech.edu/))

Explanation: What's happening at the center of spiral galaxy NGC 1097? No one is sure, but it likely involves a supermassive black hole (http://en.wikipedia.org/wiki/Supermassive_black_hole). Matter falling in (http://adsabs.harvard.edu/abs/2009arXiv0903.0313D) from a bar of stars (http://antwrp.gsfc.nasa.gov/apod/ap080622.html) and gas across the center is likely being heated by an extremely energetic region surrounding the central black hole (http://antwrp.gsfc.nasa.gov/apod/ap070114.html). From afar, the entire central region appears in the above (http://www.spitzer.caltech.edu/Media/releases/ssc2009-14/ssc2009-14a.shtml) false-color infrared (http://science.hq.nasa.gov/kids/imagers/ems/infrared.html) image as a mysterious eye (http://antwrp.gsfc.nasa.gov/apod/ap061112.html). Near the left edge and seen in blue, a smaller companion galaxy (http://antwrp.gsfc.nasa.gov/apod/ap080909.html) is wrapped in the spectacular spiral arms of the large spiral, lit in pink by glowing dust (http://nedwww.ipac.caltech.edu/level5/Mathis/Mathis1.html). Currently about 40 thousand light-years (http://chandra.harvard.edu/photo/cosmic_distance.html) from the larger galaxy's center, the gravity of the companion galaxy appears to be reshaping the larger galaxy as it is slowly being destroyed itself. NGC 1097 (http://antwrp.gsfc.nasa.gov/apod/ap061201.html) is located about 50 million light years away toward the constellation of the furnace (Fornax (http://en.wikipedia.org/wiki/Fornax)).

This image shows the Japanese Experiment Module - Exposed Facility as it looks from inside Kibo. The Japanese Experiment Module, or JEM, called Kibo -- which means "hope" in Japanese -- is Japan's first human space facility and enhances the unique research capabilities of the International Space Station. Experiments in Kibo focus on space medicine, biology, Earth observations, material production, biotechnology and communications research. Kibo experiments and systems are operated from the Mission Control Room at the Space Station Operations Facility, or SSOF, at Tsukuba Space Center in Ibaraki Prefecture, Japan, just north of Tokyo.

A Floral Aurora Corona

Explanation: Few auroras show this level of detail. Above (http://spaceweather.com/aurora/images2009/22jul09b/Zoltan-Kenwell3.jpg), a standard digital camera captured a particularly active and colorful auroral corona (http://www.exploratorium.edu/learning_studio/auroras/auroraslook.html) that occurred last week above Alberta (http://en.wikipedia.org/wiki/Alberta), Canada (http://en.wikipedia.org/wiki/Canada). With a shape reminiscent of a flower (http://www.youtube.com/watch?v=rQYjZRuAay0), the spectacular aurora (http://spaceweather.com/aurora/gallery_01jul09_page2.htm) had an unusually high degree of detail (http://antwrp.gsfc.nasa.gov/apod/ap020115.html). The vivid green and purple auroral colors (http://www.exploratorium.edu/learning_studio/auroras/difcolors.html) are caused by high atmospheric oxygen (http://periodic.lanl.gov/elements/8.html) and hydrogen (http://periodic.lanl.gov/elements/1.html) reacting to a burst of incoming electrons (http://www-istp.gsfc.nasa.gov/Education/welect.html). Many photogenic auroras (http://spaceweather.com/aurora/gallery_01jul09.htm) have been triggered from a solar wind (http://en.wikipedia.org/wiki/Solar_wind) stream that recently passed the Earth. The auroras were unexpected because the initiating Sun has been unusually quiet (http://antwrp.gsfc.nasa.gov/apod/ap080924.html) of late.

Explanation: The July 22nd total solar eclipse was the longest of the 21st century (http://science.nasa.gov/headlines/y2009/20jul_longestsolareclipse.htm). From the point of maximum eclipse along the Moon's shadow track (http://spaceweather.com/eclipses/gallery_22jul09_page4.htm) across the Pacific Ocean, the Moon completely blocked the Sun for a total of 6 minutes and 39 seconds. But from the deck of this cruise ship the duration of the total eclipse phase (http://www.mreclipse.com/Special/SEprimer.html) was extended to a whopping 6 minutes and 42 seconds by the ship's motion along the shadow track. This panoramic view of the scene shows the shimmering solar corona (http://antwrp.gsfc.nasa.gov/apod/ap090726.html) in a darkened daytime sky, with clouds silhouetted by a bright sky on the distant horizon, beyond the Moon's shadow (http://antwrp.gsfc.nasa.gov/apod/ap070610.html). Mercury can be seen near the eclipsed Sun. Venus lies near the upper right edge of the frame.

Explanation: When stars form, pandemonium reigns. A textbook (http://zebu.uoregon.edu/text.html) case is the star forming region NGC 6559 (http://antwrp.gsfc.nasa.gov/apod/ap040629.html). Visible above (http://www.caelumobservatory.com/gallery/n6559.shtml) are red glowing emission nebulas (http://antwrp.gsfc.nasa.gov/apod/emission_nebulae.html) of hydrogen (http://periodic.lanl.gov/elements/1.html), blue reflection nebulas (http://en.wikipedia.org/wiki/Reflection_nebula) of dust (http://antwrp.gsfc.nasa.gov/apod/ap030706.html), dark absorption nebulas (http://www.glyphweb.com/esky/concepts/absorptionnebula.html) of dust, and the stars that formed from them. The first massive stars (http://antwrp.gsfc.nasa.gov/apod/ap030610.html) formed from the dense gas will emit energetic light (http://imagers.gsfc.nasa.gov/ems/uv.html) and winds (http://www.peripatus.gen.nz/Astronomy/SteWin.html) that erode, fragment, and sculpt (http://antwrp.gsfc.nasa.gov/apod/ap050425.html) their birthplace.

After tens of millions of years, the dust boils (http://www.youtube.com/watch?v=J6HVTmUjgWU) away, the gas gets swept away, and all that is left is a naked open cluster (http://antwrp.gsfc.nasa.gov/apod/ap040222.html) of stars.

A Triple Sunrise Over Gdansk Bay
Credit & Copyright: Barry (%20diaconb%20at%20mcmaster%20dot%20ca) & Noemi Diacon (McMaster U. (http://engphys.mcmaster.ca/))


Explanation: How can the same Sun rise three times? Last month on Friday, 2009 July 10, a spectacular triple sunrise (http://antwrp.gsfc.nasa.gov/apod/ap060923.html) was photographed at about 4:30 am over Gdansk Bay (http://en.wikipedia.org/wiki/Gdansk_Bay) in Gdansk (http://en.wikipedia.org/wiki/Gdansk), Poland (http://en.wikipedia.org/wiki/Poland). Clearly, our Sun rises (http://antwrp.gsfc.nasa.gov/apod/ap051221.html) only once. Some optical effect is creating at least two mirages (http://antwrp.gsfc.nasa.gov/apod/ap990601.html) of the Sun -- but which effect? In the vast majority of similarly reported cases, mirages of the brightest object in the frame can be traced to reflections internal (http://en.wikipedia.org/wiki/Lens_flare) to the camera taking the images. Still, the above image is intriguing because a sincere photographer claims the effect was visible to the unaided eye (http://en.wikipedia.org/wiki/Naked_eye), and because the photographer took several (http://antwrp.gsfc.nasa.gov/apod/image/0908/IMG_9802.JPG) other (http://antwrp.gsfc.nasa.gov/apod/image/0908/IMG_9805.JPG) frames (http://antwrp.gsfc.nasa.gov/apod/image/0908/IMG_9810.JPG) that show variants of the same effect. Therefore, polite readers are invited to debate (http://bb.nightskylive.net/asterisk/viewtopic.php?f=9&t=17170) whether the above image captures a particularly spectacular example of common reflections (http://antwrp.gsfc.nasa.gov/apod/ap060121.html) inside a standard digital camera (http://www.howstuffworks.com/digital-camera.htm), shows one of the most spectacular examples of atmospheric lensing (http://www.atoptics.co.uk/) yet recorded, or was caused by something completely different (http://en.wikipedia.org/wiki/How_Not_to_Be_Seen). If the discussion (http://bb.nightskylive.net/asterisk/viewtopic.php?f=9&t=17170) converges, the consensus will be posted here at a later date.

Betelgeuse Resolved

Credit: NaCo (http://www.eso.org/instruments/naco/), VLT (http://www.eso.org/paranal/), ESO (http://www.eso.org/) Explanation: The sharpest image ever of Betelgeuse shows a mammoth star that is slowly evaporating. Betelgeuse (sounds a lot like "beetle juice"), also known as Alpha Orionis (http://en.wikipedia.org/wiki/Betelgeuse), is one of the largest and brightest stars known. The star is a familiar orange fixture easily visible (http://antwrp.gsfc.nasa.gov/apod/ap030207.html) to the unaided eye toward the constellation of Orion (http://seds.org/Maps/Stars_en/Fig/orion.html). The above recent image (http://www.eso.org/gallery/v/ESOPIA/Stars/phot-27b-09-fullres.tif.html) from the Very Large Telescope (http://en.wikipedia.org/wiki/Very_Large_Telescope) in Chile (http://en.wikipedia.org/wiki/Chile) resolves not only the face of Betelgeuse, but a large and previously unknown plume of surrounding gas. This plume gives fresh indications of how the massive star (http://aspire.cosmic-ray.org/labs/star_life/starlife_main.html) is shedding mass as it nears the end of its life. Conversely, a series of previous observations indicate that the surface of Betelgeuse has noticeably shrunk, on the average, over the past decade. If Betelgeuse (http://www.eso.org/public/outreach/press-rel/pr-2009/pr-27-09.html), a red supergiant star (http://en.wikipedia.org/wiki/Supergiant_star) about 640 light years distant, were placed at the center of our Solar System, the plume would extend past the orbit of Jupiter. Since Betelgeuse (http://antwrp.gsfc.nasa.gov/apod/ap990605.html) is known to change its brightness irregularly (http://www.aavso.org/vstar/vsots/1200.shtml), future observations may determine if changes its appearance irregularly as well. Betelgeuse (http://www.youtube.com/watch?v=pl-oR7hTTYY) is a candidate to undergo a spectacular supernova (http://www.earthsky.org/radioshows/48792/betelgeuse-could-become-supernova) explosion almost anytime in the next few thousand years.

Rollout of STS-128

Rollout of space shuttle Discovery was slow-going due to the onset of lightning in the area of Launch Pad 39A at NASA's Kennedy Space Center in Florida.

First motion of the shuttle out of the Vehicle Assembly Building was at 2:07 a.m. Aug. 4. Discovery's 13-day flight will deliver a new crew member and 33,000 pounds of equipment to the International Space Station. The equipment includes science and storage racks, a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Launch of Discovery on its STS-128 mission is targeted for late August.

Explanation: This is the mess that is left when a star explodes. The Crab Nebula (http://www.seds.org/messier/m/m001.html), the result of a supernova (http://imagine.gsfc.nasa.gov/docs/science/know_l1/supernovae.html) seen in 1054 AD (http://www.seds.org/messier/more/m001_sn.html), is filled with mysterious (http://www.youtube.com/watch?v=5VnJ9pRR8-8) filaments. The filaments (http://antwrp.gsfc.nasa.gov/apod/ap980208.html) are not only tremendously complex, but appear to have less mass than expelled (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1995ApJ...454L.129F) in the original supernova and a higher speed than expected (http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1998PASP..110..831N) from a free explosion. The above image (http://hubblesite.org/newscenter/archive/releases/2005/37/), taken by the Hubble Space Telescope (http://antwrp.gsfc.nasa.gov/apod/ap950810.html), is presented in three colors chosen for scientific interest. The Crab Nebula (http://en.wikipedia.org/wiki/Crab_Nebula) spans about 10 light-years (http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html). In the nebula's very center lies a pulsar (http://www.jb.man.ac.uk/%7Epulsar/Education/Sounds/sounds.html): a neutron star (http://www.astro.umd.edu/%7Emiller/nstar.html) as massive as the Sun (http://www.nineplanets.org/sol.html) but with only the size of a small town (http://www.cityofhoughton.com/). The Crab Pulsar (http://antwrp.gsfc.nasa.gov/apod/ap020920.html) rotates about 30 times each second.
