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

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 ...

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 ...

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 ...

Jupiter’s moon Io is the best example of a world of fire, freckled with volcanoes and cracked by lava spills. There are many competing theories to explain the workings of this fire-orb.

Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system.

Jupiter's volcanic moon Io doesn't appear to have a subsurface ocean of magma, resolving some issues about how Io's volcanoes erupt and raising broader questions about similar magma oceans within ...

On March 2, 1979, a paper in Science ruminated on Io’s strange orbit. Because of the positions and orbits of neighboring moons, Io’s orbit is elliptical rather than circular. And when Io is ...

But Io is different, with volcanic eruptions regularly remaking parts of the moon's crust. That means there's a good chance something on Io has changed since NASA's Galileo orbiter last ...

Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system.
