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 sources in the moons’ mantles may contribute to maintaining ocean warmth, while antifreeze substances like chlorides, ammonia, and salts are likely abundant in their oceans.
Re-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.
