Cassiopeia A is a supernova remnant (the remains of a massive star exploded about 220 years ago) in the constellation Cassiopeia. It is 11000 light-years away in the Milky Way. The expanding clouds of material has a temperature of around 50 million degrees Fahrenheit, and it expands at 4000-6000 km/s; It is now approximately 10 light-years across.
First Landing of Columbia
After completing the first full test of the Space Transportation System, mission STS-1, space shuttle Columbia is seen here on the Rogers dry lake, Runway 23, at NASA’s Dryden Flight Research Center in Edwards, California. From this aerial view, Columbia is seen as it is being convoyed to a parking area.
Today at 3:44 AM eastern, SpaceX launched successfully to become the first commercial company in history to attempt to visit the International Space Station. This marks the third consecutive Falcon 9 launch success and the fifth straight launch success for SpaceX.

Partial Solar Eclipse over Texas

It was a typical Texas sunset except that most of the Sun was missing.
The location of the missing piece of the Sun was not a mystery — it was behind the Moon. Sunday night’s partial eclipse of the Sun by the Moon turned into one of the best photographed astronomical events in history.
Gallery after online gallery is posting just one amazing eclipse image after another.
Pictured above is possibly one of the more interesting posted images — a partially eclipsed Sun setting in a reddened sky behind brush and a windmill.
The image was taken Sunday night from about 20 miles west of Sundown, Texas, USA, just after the ring of fire effect was broken by the Moon moving away from the center of the Sun.
Coming early next month is an astronomical event that holds promise to be even more photographed — the last partial eclipse of the Sun by Venus until the year 2117.
At the West Wall of Aristarchus Crater
Aristarchus Plateau is anchored in the vast lava flows of the Moon’s Oceanus Procellarum. At the plateau’s southeastern edge lies the spectacular Aristarchus Crater, an impact crater 40 kilometers wide and 3 kilometers deep. Scan along this remarkable panorama and you will find yourself gazing directly at the crater’s west wall for some 25 kilometers. Features along the terraced wall include dark impact melt and debris deposits, bright excavated material, and boulders over 100 meters wide. At a full resolution of 1.6 meters per pixel, the sharp mosaic was created from images recorded by the Lunar Reconnaissance Orbiter’s narrow angle camera in November of 2011. The orbiter’s vantage point was 70 kilometers east of the crater’s center and only 26 kilometers above the lunar surface.
