April Flowers for redOrbit.com - Your Universe Online In August of last year, Jupiter's moon Io surprised astronomers with three massive volcanic eruptions within a two-week period. Two studies, accepted for publication in the journal Icarus, suggest that these volcanic "outbursts" might occur more commonly than previously thought. "We typically expect one huge outburst every one or two years, and they're usually not this bright," said Imke de Pater, professor and chair of astronomy at...

Lawrence LeBlond for redOrbit.com - Your Universe Online Watching active volcanic eruptions should be done so from a safe distance. Observing active eruptions here on Earth can be easily accomplished from the comfort of your home with proper equipment. But observing an Earthen volcanic eruption from home is nothing when compared to what a group of California researchers have been privy to. Using an ingenious combination of ground-based telescopic surveys and archival data, the Golden...

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...

Jupiter's Moon Io -- Looking like a giant pizza covered with melted cheese and splotches of tomato and ripe olives, Io is the most volcanically active body in the solar system. Volcanic plumes rise 300 kilometers (190 miles) above the surface, with material spewing out at nearly half the required escape velocity. A bit larger than Earth's moon, Io is the third largest of Jupiter's moons, and the fifth one in distance from the planet. Although Io always points the same side toward...
