August 10, 2009--An astronaut aboard the International Space Station snapped this recently released shot of an ancient impact crater in Chad.

The Aorounga Impact Crater is thought to be about 370 to 345 million years old. Studies of the crater have suggested it was one of three created during the same impact event, but the other two potential craters are buried by the Sahara's sands.
