NASA's Voyager 1 took this photo of Jupiter and two of its satellites (Io, left, and Europa) on Feb. 13, 1979. Io is above Jupiter's Great Red Spot; Europa is above Jupiter's clouds. The poles are dark and reddish.
This color image of the Jovian moon Europa was acquired by NASA's Voyager 2 during its close encounter on Jul. 9, 1979. Europa, the size of our moon, is thought to have a crust of ice perhaps 100 kilometers thick which overlies the silicate crust.
This photo, taken on Jan. 9, 1979 by NASA's Voyager 1, is dominated by the Great Red Spot. Swirling, storm-like features possibly associated with wind shear can be seen both to the left and above the Red Spot.
This dramatic view of Jupiter's Great Red Spot and its surroundings was obtained by NASA's Voyager 1 on Feb. 25, 1979. The colorful, wavy cloud pattern to the left of the Red Spot is a region of extraordinarily complex end variable wave motion.
This view shows some detail and differences in the complex system of rings. This was one of the first pictures obtained once NASA's Voyager 2 resumed returning images Aug. 29, 1979 after its scan platform was commanded to view Saturn.
Both the limb of Saturn and the shadow of its ring system are seen through the transparent C-ring in this striking picture taken by NASA's Voyager 1 on Nov. 9, 1980. Gaps and regions of high transparency are seen throughout the C-ring.
