Potential Deep Subsurface Oceans on Uranus's Moon Ariel and Other Ocean Worlds
A recent study suggests that Uranus's moon Ariel likely has a deep, hidden ocean up to 100 miles beneath its icy surface, formed by tidal flexing and orbital eccentricity, which caused fractures and resurfacing, and may have frozen over in the past billion years. The presence of ammonia and surface features support the idea of a subsurface ocean, making Ariel a potential ocean world worth further exploration.
