In the new study, the authors surveyed 266 volcanic hotspots across the moon. This map showed that Io’s lower latitudes were emitting 60 percent more volcanic heat per unit area than the poles.

Io, the innermost of Jupiter's four largest moons, is slightly bigger than Earth's moon.Io is the most volcanically active body in the solar system, bursting with plumes that rise up to more than ...

This new, first-of-its-kind map of Io's heat emission shows volcanoes across the moon's surface. It encompasses nearly 30 years of data. Credit: Ashley Gerard Davies et al 2024 Planet.

Behold the volcano-blanketed moon, Io. After swooping by Jupiter's tortured moon on Feb. 3, NASA's Juno spacecraft beamed back some of the closest-ever images of this unique world. The agency's ...

Jupiter moon of Io is famed for its volcanoes. NASA just spotted the most powerful one yet Not only was the hot spot larger than Earth’s Lake Superior, but it also was seen belching out ...

Because Io is so close to its massive host planet, the moon is subjected to a tremendous gravitational pull as it orbits ...

NASA's robotic Juno spacecraft is delivering the fresh data on Io with a series of flybys, each getting closer to Jupiter's volcanic moon until a pair of close-up encounters at a range of less ...

S cott Bolton’s first encounter with Io took place in the summer of 1980, right after he graduated from college and started a job at NASA. The Voyager 1 spacecraft had flown past this moon of Jupiter, ...

Recent flybys of the fiery world refute a leading theory of its inner structure—and reveal how little is understood about geologically active moons.

Jupiter's moon Io is a volcanic hellscape—and has been since the solar system began. Io is the most volcanic body known to science, and researchers have puzzled over its history for years.
