'Family photo' of the Galilean moons
This montage shows views of Jupiter's four 'Galilean moons' as captured by the LORRI camera system on NASA's New Horizons spacecraft in 2007 as it picked up extra momentum for its target, the dwarf planet Pluto, by performing a close flyby of Jupiter. From left to right (and inside out as seen from Jupiter): Io, Europa, Ganymede and Callisto.
