Hubble Finds Evidence of Water Vapor at Jupiter’s Moon Ganymede

The video explores the discovery of water vapor in Ganymede's atmosphere, the largest moon in our solar system. Initial observations using the Hubble Space Telescope revealed differences in auroral bands, initially attributed to atomic oxygen. However, 2018 data showed minimal atomic oxygen, suggesting sublimation of surface ice as the cause. This discovery enhances our understanding of the Jovian system and the formation of gas giant planets and their moons.
