Stickney Crater
10.04.2008
Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877.
A Large Magellanic Cloud Deep Field
9.04.2008
Is this a spiral galaxy? No. Actually, it is the Large Magellanic Cloud (LMC), the largest satellite galaxy of our own Milky Way Galaxy. The LMC is classified as a dwarf irregular galaxy because of its normally chaotic appearance. In this deep and wide exposure, however, the full extent of the LMC becomes visible.
Southern Orion: From Belt to Witch
8.04.2008
Do you recognize the belt of Orion in this image? The familiar trio of stars, visible to the unaided eye, can be found across the upper left. Otherwise, the southern part of the constellation...
Mysterious White Rock Fingers on Mars
7.04.2008
What caused this unusual white rock formation on Mars? Intrigued by the possibility that they could be salt deposits left over as an ancient lakebed dried-up, detailed studies of these fingers now indicate that this is not correct.
Wisps Surrounding the Horsehead Nebula
6.04.2008
The famous Horsehead Nebula in Orion is not alone. A deep exposure shows that the dark familiar shaped indentation, visible just below center, is part of a vast complex of absorbing dust and glowing gas.

Layers in Aureum Chaos
4.04.2008
At first glance these undulating shapes in shades of blue might look like waves on an ocean. Seen here in a false-color image from the Mars Reconnaissance Orbiter's HiRISE camera, they are actually layered rock outcrops found in Aureum Chaos.
South of Orion
3.04.2008
This tantalizing array of nebulae and stars can be found about 2 degrees south of the famous star-forming Orion Nebula. The region abounds with energetic young stars producing jets and outflows that push through the surrounding material at speeds of hundreds of kilometers per second.
APOD: 2008 April 2- Globular Cluster M55 from CFHT
2.04.2008
The fifty-fifth entry in Charles Messier's catalog, M55 is a large and lovely globular cluster of around 100,000 stars. Only 20,000 light-years away in the constellation Sagittarius, M55 appears to earth-bound observers to be nearly 2/3 the size of the full moon.
APOD: 2008 April 1- New Space Station Robot Asks to be Called Dextre the Magnificent
1.04.2008
In a surprising and potentially troubling request, the new space station robot known as Dextre demanded that astronauts refer to it in the future at "Dextre the Magnificent." Brandishing power tools that would make...
