Jupiter's Family Portrait
This "family portrait," a composite of the Jovian system, includes the edge of Jupiter with its Great Red Spot, and Jupiter's four largest moons, known as the Galilean satellites. From top to bottom, the moons shown are Io, Europa, Ganymede and Callisto.

Jupiter's Moons in 1979: Ganymede by Voyager 2
This image shows Jupiter moon Ganymede taken by Voyager 2 in 1979. Voyager probes 1 and 2 visited the Jovian system in 1979, before taking different paths through the outer reaches of the Solar System, studying the giant planet as well as making numerous images of its moons. The relatively narrow field of view, combined with the Voyager probes' close flybys meant that the photos had to be stitched together, which in the days before powerful computer graphics software meant printing them out and sticking them together by hand, like a giant jigsaw puzzle, interspersed with hand-written notes and computer printouts of technical information relating to the photographs.
