NASA's Cassini spacecraft captured this image showing Saturn's icy moon Rhea taking center stage, with cameo appearances by Saturn's rings and three clearly visible moons. In this image, Dione appears just above Rhea. Tethys is the larger circle toward the upper left and Epimetheus is the smaller dot to the left of Rhea. Prometheus is to the left of Dione, but barely distinguishable as a speck embedded in the rings. This wide-angle image was taken on Jan. 11, 2011 from a distance of approximately 60,000 kilometers away (37,000 miles).
