NASA's Hubble Space Telescope Discovers Water Vapor On Jupiter's Moon
The astronomers for the first time by using new and archived datasets from NASA's Hubble Space Telescope have discovered evidence of water vapor in Jupiter's moon's atmosphere, Ganymede. The water vapor was likely to have formed due to sublimation, turning solid ice into gas. Ganymede is the largest moon in our solar system and research suggests that it may contain more water than all of Earth's oceans together.
