This mosaic of Jupiters moon Ganymede consists of more than 100 images acquired with NASAs Voyager and Galileo spacecrafts, showing irregular lumps beneath the icy surface.
Natural color view of Ganymede from NASA's Galileo spacecraft during its first encounter with the satellite. The dark areas are the older, more heavily cratered regions and the light areas are younger, tectonically deformed regions.
Topographic detail is seen in a stereoscopic view of this part of Jupiter's moon Ganymede. This image is a computer reconstruction from two images taken by NASA's Galileo spacecraft in 1996.
