NASA's Cassini spacecraft captured this image of shadow-striped Saturn and its exquisitely thin rings, with its moon Rhea hanging as a crescent in the distance. A couple of bright pixels at the center of the image mark the location of the tiny moon Pan, 26 kilometers (16 miles) across.
As Saturn's second-largest moon, Rhea is 1,528 kilometers (949 miles) wide. Cassini took the image on Feb. 3 in visible light with its narrow-angle camera, at a distance of approximately 4.1 million kilometers (2.5 million miles) from Saturn and 4.6 million kilometers (2.9 million miles) from Rhea. The image scale is 28 kilometers (17 miles) per pixel on Rhea.
