Ganymede May Have An Ocean That Could Harbour Life

Ganymede is not only Jupiter’s largest moon but the largest moon in the solar system. Until recently, it was thought that due to the high pressures Ganymede had an ocean sandwiched between two layers of ice. However, a recent study suggests that Ganymede may in fact have multiple layers of ice and oceans. The interesting part is that it would appear that a salty ocean could well be in contact with the rocky core. This ocean/rock interface may be able to support life. This is an interesting finding as Ganymede is larger than planet Mercury so its oceans are huge and this increases the likelihood of life being supported.
