Astronomy Picture Of the Day (APOD)
Endeavour in the Moon
20.11.2008
Glaring near the top of the frame, the shuttle orbiter Endeavour rockets into the night on the STS-126 mission. Endeavour left planet Earth on November 14 from Launch Pad 39A at NASA's Kennedy Space Center, making the 27th flight to the International Space Station.
Unusual Auroras Over Saturns North Pole
19.11.2008
What's causing this unusual aurora over Saturn? No one is sure. Infrared images by the robotic Cassini spacecraft of the north pole of Saturn have uncovered aurora unlike any other seen previously in our Solar System.
Restored: First Image of the Earth from the Moon
18.11.2008
Pictured above is the first image ever taken of the Earth from the Moon. The image was taken in 1966 by Lunar Orbiter 1 and heralded by then-journalists as the Image of the Century. It was taken about two years before the Apollo 8 crew snapped its more famous color cousin.
HR 8799: Discovery of a Multi planet Star System
17.11.2008
How common are planetary systems like our own Solar System? In the twelve years previous to 2008, over 300 candidate planetary systems have been found orbiting nearby stars. None, however, were directly imaged, few showed evidence for multiple planets, and many had a Jupiter-sized planet orbiting inside the orbit of Mercury.
Anticrepuscular Rays Over Colorado
16.11.2008
What's happening over the horizon? Although the scene may appear somehow supernatural, nothing more unusual is occurring than a setting Sun and some well placed clouds. Pictured above are anticrepuscular rays. To understand them, start by picturing common crepuscular rays that are seen any time that sunlight pours though scattered clouds.
Arp 273
15.11.2008
The two prominent stars in the foreground of this colorful skyscape are well within our own Milky Way Galaxy. Their spiky appearance is due to diffraction in the astronomer's telescope. But the two eye-catching galaxies in view lie far beyond the Milky Way, at a distance of about 200 million light-years.
Fomalhaut b
14.11.2008
Fomalhaut (sounds like "foam-a-lot") is a bright, young, star, a short 25 light-years from planet Earth in the direction of the constellation Piscis Austrinus. In this sharp composite from the Hubble Space Telescope, Fomalhaut...
A Bubble in Cygnus
13.11.2008
Adrift in the rich star fields of the constellation Cygnus, this lovely, symmetric bubble nebula was only recently recognized and may not yet appear in astronomical catalogs. In fact, amateur astronomer Dave Jurasevich identified...
Phoenix and the Holy Cow
12.11.2008
The northern Martian summer is waning. As predicted, a decline in daylight hours, deteriorating weather, and dust storms are preventing solar arrays on the Phoenix Mars Lander from providing power. Phoenix's last signal...
The Cosmic Web of the Tarantula Nebula
11.11.2008
First cataloged as a star, 30 Doradus is actually an immense star forming region in nearby galaxy The Large Magellanic Cloud. The region's spidery appearance is responsible for its popular name, the Tarantula nebula, except that this tarantula is about 1,000 light-years across, and 180,000 light-years away in the southern constellation Dorado.
