NASA's Juno spacecraft was dispatched on a mission in 2011 to study the planet Jupiter. It has beamed back some truly stunning images and valuable data on the solar system's largest planet. While in ...

A new analysis of data from NASA’s Galileo spacecraft reveals a subsurface “ocean” of magma–either molten or partially molten–beneath the surface of Jupiter’s volcanic moon Io. The finding, from a ...

Investigations into lava lakes on the surface of Io, the intensely volcanic moon that orbits Jupiter, may provide clues to what Earth looked like in its earliest phases, according to researchers at ...

Io is a violent world. Tortured by the gravitational forces of Jupiter, it erupts with sulphur and lava. Our own planet has volcanoes and lava flows, but it pales in comparison to Io. From Earth, ...
