Miranda's Hidden Ocean Reframes the Search for Life on Uranus' Moon

A Planetary Science Journal study reexamining Voyager 2 data suggests Miranda, a moon of Uranus, could have hosted a deep subsurface ocean (potentially ≥100 km) in the last 100–500 million years, with tidal heating possibly keeping liquid water inside. While conclusive evidence of life isn’t found, this makes Miranda a notable candidate in the broader search for extraterrestrial life and informs the Drake Equation’s life-fraction term.
