Io's orbit cuts across Jupiter's powerful magnetic lines of force, turning Io into an electric generator. According to NASA , Io can develop 400,000 volts across itself, in turn creating 3 million ...

Because Io is so close to its massive host planet, the moon is subjected to a tremendous gravitational pull as it orbits Jupiter once about every 42 hours, according to the Planetary Society.

Jupiter's moon Io is the solar system's most volcanic body thanks to a gravitational tug of war that rages below its surface. But now scientists know the violent moon has always been this way.

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 ...

Jupiter sets record after 12 new moons discovered 00:14. A NASA spacecraft made its closest-ever approach to Jupiter's moon Io, coming within 930 miles of the "surface of the most volcanic world ...

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.

The Io–Jupiter system is similar, in scale, to an exoplanet orbiting an M-dwarf, and if volcanic Io doesn't have a magma ocean then perhaps exoplanets on close orbits around M-dwarfs don't either.

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

Flybys of Jupiter’s moon Io, the only known volcanic world in our solar system, have captured images of a massive lava lake and a towering Matterhorn-like mountain. CNN values your feedback 1.

The mutilated surface of Jupiter’s moon Io was revealed in great detail by the Juno spacecraft, which has been exploring the Jovian system since 2016 and recently pulled off the closest flyby of ...

Also published is a compilation of Juno's images of Io taken on Oct. 16, as well as another photo showing both Io and Jupiter in the same field of view.. Io is the fifth most distant moon from ...

An artist’s concept of a lava lake on Jupiter’s moon Io called Loki Patera. The image was made using data from the JunoCam imager aboard NASA’s Juno spacecraft.
