Io, Jupiter’s most volcanically active moon, defies long-held theories about its geological chaos. Contrary to previous assumptions, a new study suggests that the moon’s 400 volcanoes are powered by scattered magma chambers in its solid mantle, rather than a global ocean of magma.
Researchers used data from NASA’s Juno spacecraft and historical observations of Io’s tidal deformations to reach their conclusion. They found that the moon’s internal heat, generated by tidal flexing, is sufficient to power volcanic activity without requiring a large, surface-dwelling magma ocean.
The discovery challenges previous theories about how Io’s volcanoes are fueled and has significant implications for our understanding of planetary formation and evolution. The study also provides valuable insights into the effects of tidal flexing on moon interiors and can inform future research on other moons and exoplanets.
