Latest Moon Io Stories
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.
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 the 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.
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.
