New mapping of Io ( Jupiter )

A group of scientists led by the Arizona State University (U.S.) has created the first geological map of the entire surface of the moon Io.

The satellite of Jupiter discovered by Galileo in January 1610, and have had to spend 400 years to be mapped with great accuracy and detail its relief and its more than 400 volcanoes.

Map, that combines the best images from the Voyager spacecraft 1 and 2 the NASA and the Galileo orbiter (1995-2003) developed with a high level of detail a series of volcanic features as volcanic domes and depressions, lava fields and plume deposits in various forms, sizes and colors, addition of high mountains and great plains rich in sulfur dioxide. And total, identified 425 volcanoes. (Notiweb)

It is the most volcanically active object in the Solar System, as recognized by observations from six National Aeronautics and Space Administration (NASA) spacecraft: Voyager 1 (March 1979), Voyager 2 (July 1979), Hubble Space Telescope (1990–present), Galileo (1996–2001), Cassini (December 2000), and New Horizons (February 2007) (USGS)
