Color views from Galileo were superimposed on higher-resolution monochrome images. CREDIT: USGS View full size image <javascript:void(0);> For the first time, scientists have created a global geologic map of Jupiter's moon Io, the most volcanically active object in the solar system. The map, which was published this week by the U.S. Geological Survey (USGS), shines a light on Io, the fourth-largest satellite in thesolar system <http://www.space.com/56-our-solar-system-facts-formation-and-discovery. html>. Scientists hope the new tool will help them better understand the exotic moon, which boasts volcanic activity 25 times that of Earth. "This new map of Io's geology provides for the first time a detailed record of the different types of landforms and deposits that form the surface and presents a global context that is important for understandingIo's internal evolution <http://www.space.com/11647-jupiter-volcanic-moon-io-magma-ocean.html>an d volcanic processes, as well as for targeting future observations of Io," David Crown, of the Planetary Science Institute in Tucson, Ariz., said in a statement. "Knowledge of Io's volcanic activity derived from geologic mapping is an important contribution to our understanding of the nature and diversity of volcanism in our solar system," added Crown, who helped put the map together.
