    Original Caption Released with Image: 
    This global mosaic shows the highest resolution Galileo images availableof 
    Jupiter's moon, Io. North is to the top of the picture. The images,obtained 
    at low sun illumination angles (high sun-target-spacecraft angles)which 
    emphasize topographic shadows, were taken by the Solid State Imaging(SSI) 
    system on NASA's Galileo spacecraft over the course of several orbits.The 
    grid identifies the names and locations of several of Io's main 
    features.Several active but as yet unnamed volcanic features are indicated 
    by arrows.While volcanic centers are rather evenly distributed, almost all 
    of the activeplumes and long-lived hot spots seen over the span of NASA's 
    Galileo missionat Jupiter or during the flyby's of NASA's Voyager spacecraft 
    in 1979are within 30 degrees of the equator.
