Quote from Wikipedia: "Gliese 581d is an extrasolar planet orbiting the star Gliese 581 approximately 20 light-years away in the constellation of Libra. Because of its mass, between 7 and 14 times that of Earth, the planet is classified as a super-Earth. In late April 2009, new observations by the original discovery team concluded that the planet is within the habitable zone where liquid water may exist".

Edit 7/19/10: After reading Siamon89's comment I brightened it a bit. I also added a 1920X1080 which wasn't in the original download.
