An image of Uranus and its rings and surrounding moons labeled Ariel, Puck, Miranda, Umbriel, Oberon and Titania from May 12, 2023 taken by the James Webb Space Telescope. Text, Water on Uranus' Moons?
Uranus' four largest moons likely contain deep ocean layers beneath their icy surfaces, according to a new study.
Image of Titania from Voyager 2 on May 12, 2023. Text, The new findings contradict the idea that smaller moons could not retain enough heat to keep their oceans from freezing.
Scientists re-analyzed data from multiple missions, including Voyager 2 which visited Uranus, plus Galileo, Cassini, and New Horizons, which visited similar small icy worlds.
The large moons Titania and Oberon may get heat from hot liquid released in their rocky interiors.

The study will help scientists plan future missions to the Uranus system, which has been named a science priority by the U.S. National Academies.
