NASA’s Hubble Space Telescope has detected water vapour in the atmosphere of Ganymede, Jupiter’s largest moon. This groundbreaking discovery suggests that the moon could have a thin atmosphere and possibly subsurface oceans. Ganymede, already known for its magnetic field and icy surface, now adds another intriguing feature to its profile. The water vapour is believed to have formed as ice on the surface sublimated directly into gas. Scientists are now looking deeper into Ganymede’s potential for supporting life or future exploration.
