New Massive Volcano Discovered on Jupiter’s Moon Io

NASA's Juno spacecraft captures images of a newly formed volcano with extensive lava flows and sulfur deposits.

The new volcanic feature on Io, the most geologically active body in the solar system, was identified in JunoCam images from February 2024.
This volcano, located just south of Io's equator, was absent in images from the Galileo spacecraft taken in 1997.
The volcanic area spans approximately 180 kilometers by 180 kilometers, with lava flows and sulfur deposits marking its landscape.
JunoCam's observations revealed nine plumes associated with active volcanic features and other surface changes, including new lava flows.
Scientists are studying Io's volcanic activity to better understand its interior composition and the mechanisms driving its eruptions.
