The work is based on new modeling and explores how oceans could exist in unlikely places in our solar system. New computer modeling and re-analysis of Voyager data suggest that four of Uranus' largest moons likely have ocean layers between their cores and icy crusts. Insulation and potential heat

The National Academies’ 2023 Planetary Science and Astrobiology Decadal Survey prioritized exploring Uranus. In preparation for such a mission, planetary scientists are focusing on the ice giant to bolster their knowledge about the mysterious Uranus system.
In fact, Miranda, the innermost and fifth largest moon, also hosts surface features that appear to be of recent origin, suggesting it may have held enough heat to maintain an ocean at some point. The recent thermal modeling found that Miranda is unlikely to have hosted water for long: It loses heat too quickly and is probably frozen now.
Of course, there still are a lot of questions about the large moons of Uranus, Castillo-Rogez said, adding that there is plenty more work to be done: “We need to develop new models for different assumptions on the origin of the moons in order to guide planning for future observations.”

Study of Uranus' large moons shows four may hold waterRe-analysis of data from NASA's Voyager spacecraft, along with new computer modeling, has led NASA scientists to conclude that four of Uranus' largest moons likely contain an ocean layer between their cores and icy crusts. Their study is the first to detail the evolution of the interior makeup and structure of all five large moons: Ariel, Umbriel, Titania, Oberon, and Miranda. The work suggests four of the moons hold oceans that could be dozens of miles deep.
