Fact Sheet
Hot Moon
A plume of hot gas erupts from a volcano on Jupiter's moon Io in this pair of false-color images from the Galileo spacecraft. The plume, photographed in August, rises about 370 miles (600 km) above Io's surface. Its parent volcano had not been seen before the August encounter, and has not yet been named. Galileo was scheduled to fly close to Io again on Monday.
