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 ...

NASA has recorded the most powerful volcanic eruption outside of Earth on Io, one of Jupiter’s moons. On December 27, 2022, Juno, NASA’s spacecraft, witnessed numerous active volcanoes erupting ...

NASA’s Juno probe began orbiting Jupiter a little more than two years ago, and it has already returned heaps of valuable data that scientists are now analyzing to better understand our solar system’s ...

NASA is unraveling Io's volcanic secrets. The space agency's Juno spacecraft has been swooping progressively closer to Jupiter's profoundly volcanic moon Io, and its observations reveal the full scope ...

The amount of lava gushing from individual volcanoes on Jupiter's moon Io dwarfs earthly comparisons, and the pace at which lava is repainting Io's surface suggests a novel technique for determining ...

JunoCam, the visible light imager aboard NASA’s Juno, captured this enhanced-color view of Jupiter’s northern high latitudes from an altitude of about 36,000 miles (58,000 kilometers) above the giant ...

NASA recently shared a close-up image of Jupiter's Moon Io, taken by the Juno spacecraft during its final close flyby on February 3. The spacecraft approached within 1,500 kilometres of Io, capturing ...

More than 400 years after Galileo's discovery of Io, the innermost of Jupiter's largest moons, a team of scientists has produced the first complete global geologic map of the Jovian satellite. More ...
