The image was part of an extensive sequence of "volcano watch" pictures of Io. The sunlit crescent of Io is seen at the left, and the night side illuminated by light reflected from Jupiter can also be seen. Three volcanic eruption plumes are visible on the limb. All three were previously seen by Voyager 1. On the bright limb Plume 5 (upper) and Plume 6 (lower) are about 100 kilometers high, while Plume 2 on the dark limb is about 185 kilometers high and 325 kilometers wide. The "volcano watch" sequence of pictures told us that these volcanoes are persistent, change with time, and are larger and last longer than those on Earth. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/PIA02254/PIA02254.dc.xml Tue, 10 Jul 1979 12:00:00 GMT Jupiter and its moons. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GPN-2000-000451/GPN-2000-000451.dc.xml Jupiter and its four planet-sized moons, called the Galilean satellites, were photographed in early March 1979 by Voyager 1 and assembled into this collage. Io is the moon in the upper left corner of the image, and is the moon that is closest to Jupiter. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GPN-2000-000451/GPN-2000-000451.dc.xml Thu, 01 Mar 1979 12:00:00 GMT
