NASA’s Juno mission revealed that Jupiter’s moon, Io, the most volcanic body in our solar system, doesn’t possess a global magma ocean. Instead, separate magma chambers fuel its over 400 active volcanoes, solving a 44-year-old mystery. Juno’s gravity data, collected during recent flybys, confirms this, impacting our understanding of other moons and exoplanets.
