Jupiter System Montage — Photographed in early March 1979 by Voyager 1 and assembled into this collage, not to scale but in their relative positions. Reddish Io (upper left) is nearest Jupiter; then Europa (center); Ganymede and Callisto (lower right).
Wait, my mistake, it is a moon. Many moons to be exact, out in the depths of our solar system, and NASA’s interplantary probes have provided us all with pictures of these widely scattered satellites. As these moons as further explored, we have found that they may be better locations for manned missions and even the search for life, than perhaps their gaseous gravuty well homeworlds. Let’s take a look at some of the photos of these plantoids from the Great Images in NASA library!
