Rings

NASA announced the winners of its contest to choose the best photograph taken by the Cassini spacecraft as it nears its second anniversary at the planet Saturn. NASA also announced winners of its Mars rovers' photo contest.

The winning photographs are presented in order. However, one of our favorites (photo 16) wasn't even nominated.

The winner: New details of Saturn's rings were captured when the Cassini spacecraft took photos while in the shadow of the planet.
