🌋 Meet Jupiter's volcanic moon Io! 🌋⁠ ⁠ Io is the most volcanically active body in the Solar System.⁠ ⁠ 🧲 It has a metallic core (iron iron sulfide), a partially molten silicate mantle, and a rocky crust topped with sulfur frost.⁠ ⁠ 💥 Io’s heat doesn’t come from radioactive decay like Earth’s. Instead, Jupiter’s massive gravity stretches and squeezes Io as it orbits, creating tidal heating that keeps its insides burning.⁠ ⁠ 🌋 That heat fuels 400 active volcanoes, reshaping the moon non-stop

Jupiter's moon Io is the most volcanically active body in the solar system. Our #JunoMission collected data during multiple close flybys of Io, and analysis suggests that each volcano is likely powered by its own magma chamber, rather than a subsurface ocean of magma: https://www.missionjuno.swri.edu/news/juno-uncovers-heart-of-jovian-moon-s-volcanic-rage | NASA Solar System Exploration

👉Juno Discovers Largest Volcanic Eruption on Io NASA's Juno spacecraft has captured the most significant volcanic eruption ever witnessed on Io, one of Jupiter's moons and the most volcanically active place in our solar system. This enormous eruption covered a vast area of Io’s surface with lava and debris, showcasing the powerful forces shaping the moon. Scientists believe that the immense gravitational pull from Jupiter causes tidal stresses on Io, generating enough heat to trigger these viol
