Jupiter seen by Voyager 1 by NASA: One image was taken every Jupiter day (approximately 10 hours). These pictures were taken from 01/06 to 02/03, 1979 ; and Voyager 1 flew from 58 million to 31 million kilometers from Jupiter during that time. The small, round, dark spots appearing in some frames are the shadows cast by the moons passing between Jupiter and the Sun, while the small, white flashes around the planet, are the moons themselves...

Rhea, like many moons in the outer solar system, appears dazzlingly bright in full sunlight. This is the signature of the water ice that forms most of the moon's surface, as seen by NASA's Cassini spacecraft.
