Summary:
- Ariel, one of Uranus's moons, may have had a deep ocean in its past, according to evidence found by scientists.
- The evidence includes features on Ariel's surface that suggest the presence of a former subsurface ocean, such as chaotic terrain and extensional faults.
- This discovery provides insights into the geological history and potential habitability of Ariel, which could help scientists better understand the formation and evolution of icy moons in our solar system.
