Saturn's moon Mimas may have a vast ocean hidden beneath its icy surface, according to a new study. The researchers analyzed images collected over 13 years by the Cassini mission and concluded that Mimas' rotation and orbit could only be explained by the presence of an ocean. The ocean is believed to be about 70 kilometers deep and formed within the last 25 million years. This finding challenges the idea that habitable conditions are limited to a few celestial bodies and suggests that there may be many more promising places for life in the solar system.
The finding 'makes you think that maybe you have habitability conditions in many, many, many other objects in the solar system,' says study co-author Valéry Lainey.
