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 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'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.

Jupiter’s third-largest moon Io is the most volcanically active world in our solar system. New radio images by the ALMA telescope array show the direct effect of this volcanic activity on the ...

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 ...

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 ...

ESA's Mars Express orbiter captured footage of the Mars' moon Deimos pass in front of Ganymede, Europa, Jupiter, Io and ...

The study authors figured that Jupiter’s gravity must therefore be constantly kneading Io, pulling its surface up and down by up to 100 meters, and, per their calculations, generating a lot of ...

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, ...

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.
