NASA's Juno mission reveals Io's volcanoes are fueled by distinct magma chambers, not a global ocean.

NASA's Juno mission to Jupiter has found that Io's volcanoes are powered by individual magma chambers, not a global magma ocean as previously thought. The spacecraft's close flybys collected precise data, revealing that tidal forces cause internal heat but do not create a widespread magma layer. This discovery changes our understanding of Io and could affect theories about other moons and exoplanets.
