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 moon Io has been continuously shaped by volcanic activity for billions of years — possibly even for the Solar System’s entire 4.57-billion-year history, a study suggests. The ...

Since the late 1970s, scientists have believed that Io could have an ocean of lava hidden beneath its surface, causing much of the Jovian moon’s surface-level volcanic activity.

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.

Io is Jupiter's third-largest moon, spanning roughly 2,300 miles (3,700 kilometers) across, which makes it slightly bigger than Earth's moon. It orbits Jupiter at a distance of around 262,000 ...

Ancient volcanic heat may have shaped the moon from the inside out, keeping one side thinner, warmer and more geologically active than the other, a new study suggests.

The team have even used the same technique to map the internal structures of Jupiter's volcanic moon Io and the Vesta asteroid. Article continues below "Our technique isn’t restricted just to Io ...
