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.
The NASA website hosts a large number of images from the
Soviet/
Russian space agency, and other non-American space agencies. These are not necessarily in the public domain.
The
SOHO (ESA & NASA) joint project implies that all materials created by its probe are copyrighted and require permission for commercial non-educational use.
