Io Shown in Lambertian Equal Area Projection and in Approximately Natural Color
Voyager 1 computer color mosaics, shown in approximately natural color and in Lambertian equal-area projections, show the Eastern (left) and Western (right) hemispheres of Io. This innermost of Jupiter's 4 major satellites is the most volcanically active object in the solar system. Io is 2,263 mi (3,640 km) in diameter, making it a little bigger than Earth's moon. Almost all the features visible here have volcanic origins, including several calderas and eruption plumes that were active at the time of the Voyager 1 encounter.
The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
