Juno detected tidal deformations that align with a model of Io having a partially molten but mostly solid interior. These findings are supported by observations of volcanic heat flow distribution ...

On March 9, 1979, Linda Morabito discovered a volcanic plume on Io, a moon of Jupiter, in one of the photos from Voyager 1. She wrote, “I could feel tears begin to roll down my face at the sight ...

The images (a) and (b) show hot spots and volcanoes in the south polar region overlaid over a detailed image of Io; (c) and (d) show hot spots and volcanoes in the north polar region. The ...

Io is the most volcanic body known to science, and researchers have puzzled over its history for years. A new report suggests it was born this way. This image revealing the north polar region of ...

A new volcano has been spotted on Jupiter’s moon Io, the most geologically active place in the Solar System. Analysis of the first close-up images of Io in over 25 years, captured by the JunoCam ...

“We can see that this body is completely covered with volcanoes over both poles and all across its middle, (which are) constantly going off.” The new data suggests that Io’s numerous ...

Jupiter's satellite Io is one of its largest moons. Credit: NASA / JPL-Caltech NASA's Juno spacecraft has made several close swoops by Jupiter's volcanic moon Io, and it's beamed back stunning ...

The hellish surface of a moon of Jupiter known as Io is riddled with hundreds of lava-spewing volcanoes that make the world one of chaos and violence. The brutal conditions also make Io intriguing ...

Recent strange activity around Jupiter’s volcanic moon, Io, confused and excited scientists. By Oliver Whang Io, the third largest of Jupiter’s moons, is caught in a pressurized, explosive dance.
