JWST Examines Jupiter's Moons in Groundbreaking Study

NASA's James Webb Space Telescope (JWST) has made significant discoveries about Jupiter's moons, Io and Ganymede. For Io, researchers detected sulfur monoxide (SO) gas and observed active volcanoes on its surface. Ganymede, the largest moon in the solar system, showed the presence of hydrogen peroxide in its polar regions. These findings provide insights into the influence of Jupiter's massive gravity on the volcanic activity of these moons. The discoveries were made using JWST's Near-Infrared Spectrograph (NIRSpec) instrument.
