The volcanic hot spot is larger than Lake Superior, spewing eruptions six times the total energy of all of the world's power plants. Reading time 3 minutes Jupiter’s moon Io is covered in hundreds of ...

The moon spent a few million years as a volcanic wasteland, covered with ongoing eruptions that spewed from mountains and even from the ground itself. New research suggests that the moon's orbit could ...

Jupiter's moon Io stands alone among the solar system's moons. It has more than 400 active volcanoes, and its surface is home to more than 100 massive volcanic mountains, some of which are taller than ...

While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor ...

Research into Jupiter’s moons shows Io and Europa did not evolve apart but formed with opposite compositions from the beginning.

How big can volcanic eruptions get on Jupiter’s moon, Io? This is what a recent study published in the Journal of Geophysical ...

A celestial conjunction event featuring Venus and Spica is anticipated for November 3. Jupiter is expected to display a multi-phase transit phenomenon involving Io and its shadow, along with Europa's ...

A new analysis of data from NASA’s Galileo spacecraft reveals a subsurface “ocean” of magma–either molten or partially molten–beneath the surface of Jupiter’s volcanic moon Io. The finding, from a ...

Europa’s buried ocean has made it one of the most exciting places to search for life beyond Earth. However, new calculations suggest its seafloor may be calm, cold, and largely inactive, with little ...

This first-ever complete map of Jupiter's volcanic moon Io released on March 19, 2012, was created using data and images from NASA's Galileo spacecraft, (which studied Jupiter and its moons between ...
