PIA00081_Ganymede_Voyager_2_mosaic.jpg - Wikipedia

Summary

Description	The hemisphere of Ganymede that faces away from Jupiter displays a great variety of terrain. In this Voyager 2 mosaic, photographed at a range of 300,000 kilometers, the ancient dark area of Regio Galileo lies at the upper right. Below it, the ray system is probably caused by water-ice, splashed out in a relatively recent impact. The original NASA image has been cropped, and some non-full-color areas have been blacked out.
