NASA's Juno Reveals Volcanic Secrets of Jupiter's Moon Io

Closest flybys in over two decades offer new insights into Io's intense volcanic activity.

NASA's Juno spacecraft captures stunning images of Io, Jupiter's moon, revealing its volcanic activity.
The recent flybys are the closest encounters with Io in over 20 years, offering new insights into its volcanic phenomena.
Scientists are investigating whether Io's volcanism is driven by a global magma ocean or a hot metal core.
Io's intense volcanic activity is fueled by tidal forces from Jupiter and its moons, Europa and Ganymede.
The Juno mission, extended through September 2025, aims to explore Jupiter's entire system, including its moons and rings.
