NASA’s Juno mission just dropped a cosmic bombshell : Jupiter’s fiery moon Io isn’t powered by a single magma ocean but hundreds of individual magma chambers!
This solves a 44-year-old puzzle about the solar system’s most volcanic body. Talk about a glow-up!
Io, Earth’s moon-sized sibling, has over 400 active volcanoes that paint its surface with lava and plumes →
. But how? Juno’s daring flybys in 2023 and 2024—skimming just 1,500 km above its ‘pizza-faced’ crust—revealed secrets hidden in gravity data.
Scientists tracked tiny spacecraft wobbles to map Io’s molten heart.
The verdict? ‘Tidal flexing’ from Jupiter’s gravity squeezes Io like a stress ball, but instead of one magma ocean, each volcano has its own magma chamber. Lead researcher Ryan Park called it a ‘game-changer’ for understanding moons like Europa and even distant exoplanets.
Next time you gaze at Jupiter, remember: Io’s raging volcanoes are basically the solar system’s ultimate group project.
