Juno has uncovered the largest known hot spot on Io, the most geologically active moon in the Solar System. This record-breaking discovery spans 100,000 km², making it 2.5 times larger than the Sea of Azov and nearly three times the size of Juno’s previously identified Loki Patera. The immense heat output—equivalent to 80 trillion watts—six times Earth’s total power production—is so intense that it saturated JIRAM’s infrared detector during observation in the Southern Hemisphere. Scientists believe this single spot is part of a larger subsurface magma chamber network, linking powerful eruptions capable of leaving long-lasting traces. This discovery underscores Io’s extreme volcanic activity and sets a new benchmark for future studies on Jupiter’s moons.
