Summary:
- Miranda, one of Uranus' moons, has an unusual and unexpected geological feature - an ocean hidden beneath its icy surface.
- This discovery challenges our understanding of how moons form and evolve, as Uranus is a very cold and distant planet, making the existence of a subsurface ocean surprising.
- The potential for life to exist in this ocean has scientists excited, as it opens up new possibilities for finding habitable environments in our solar system beyond Earth.
