What's Heating Up Io?
2012-06-11 07:45:48

A new study finds that the pattern of heat coming from volcanoes on Io's surface disposes of the generally-accepted model of internal heating.  The heat pouring out of Io's hundreds of erupting volcanoes indicates a complex, multi-layer source.  These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the June issue of the journal Icarus. A map of hot spots, classified by the amount of heat being emitted, shows the global distribution...

Geologic Map Reveals Io's Otherworldly Volcanoes
2012-03-21 04:41:48

A team of scientists led by Arizona State University has produced the first complete geologic map of Jupiter´s moon, Io. Published by the US Geological Survey, the new map reveals geologically unique features, volcanoes, and lava flows as well as some relative ages of the moon. Galileo first discovered Io more than 400 years ago. Io is the largest and innermost moon to orbit the planet Jupiter and has been the subject of many scientific studies as well as intense observation. Existing...

NASA said on Thursday that its Galileo spacecraft has revealed a subsurface ocean of molten, or partially molten, magma beneath the surface of Jupiter's volcanic moon Io. The research is the first direct confirmation of this kind of magma layer at Io and explains why the moon is the most volcanic object known in the solar system. "Scientists are excited we finally understand where Io's magma is coming from and have an explanation for some of the mysterious signatures we saw in some of the...
