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. Image credit: NASA/JPL/SSI
