A photograph taken by the Cassini space craft orbiting Saturn. Above is the south pole of Saturn’s moon Rhea (about 1,528 kilometers diameter) and in the background the moon Dione (1,123 kilometers diameter), with its southern part covered by Saturn’s rings, seen almost edge on, in front of Dione.

What a time we live in where we can see crystal clear images of moons of Saturn and its rings!
