A stunning crescent view of Saturn and its moon Rhea, captured by the Cassini spacecraft. Rhea is seen as a dark orb silhouetted against Saturn's softly lit atmosphere. The rings of Saturn appear as a thin line across the center, due to Cassini's viewing angle. This image is a still from a sequence showing Rhea's transit across Saturn.
