Craggy Craters on Rhea
This raw image obtained by NASA's Cassini spacecraft of Saturn's moon Rhea shows craters in an area between day and night on the icy moon. Cassini's wide-angle camera was about 200 kilometers (100 miles) away from Rhea's surface when the image was taken. The bright spot to the right is likely a cosmic ray hit.
