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.
