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

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

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.

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 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 ...

When Io is closer to Jupiter on its wonky orbit, it experiences a stronger gravitational pull; when it’s more distant, the gravitational pull of Jupiter is a little weaker.

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 ...

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 ...

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 ...

This gas giant has some really unique features that make it stand out. If you’re curious about space, learning a few things ...

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.
