This view, taken on October 26, 1996, during Galileo's second orbit of Jupiter, shows a crescent Ganymede and Io.  Missing pieces of Ganymede and Io are filled in from other orbits (the tips of Io's red crescent and a small portion of Ganymede's center).  The color is taken from other orbits.  This image was taken for the purpose of optical navigation, but it is still a pretty view.
