NGC 4650A: Strange Galaxy and Dark Matter
25.06.1998

This strangely distorted galaxy of stars is cataloged as NGC 4650A. It lies about 165 million light-years away in the southern constellation Centaurus. The complex system seems to have at least two parts, a flattened disk of stars with a dense, bright, central core and a sparse, sharply tilted ring of gas, dust and stars.

Nebulas Surrounding Wolf Rayet Binary BAT99 49

Enceladus Backlit by Saturn
8.02.2012

This moon is shining by the light of its planet. Specifically, a large portion of Enceladus pictured above is illuminated primarily by sunlight first reflected from the planet Saturn. The result is that the normally snow-white moon appears in the gold color of Saturn's cloud tops.

Saturn at Night
