🌋 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
