The researchers used that modeling to gauge how porous the Uranian moons' surfaces are, finding that they're likely insulated enough to retain the internal heat that would be needed to host an ocean. The authors built computer models infused with additional findings from NASA's Galileo, Cassini, Dawn, and New Horizons (each of which discovered ocean worlds), including insights into the chemistry and the geology of Saturn's moon Enceladus, Pluto and its moon Charon, and Ceres-all icy bodies around the same size as the Uranian moons. The study revisited findings from NASA's Voyager 2 flybys of Uranus in the 1980s and from ground-based observations.

This paper investigates what those could be and how they are relevant to the many bodies in the solar system that could be rich in water but have limited internal heat.'Ī recent NASA Hubble Space Telescope view reveals Uranus surrounded by its four major rings and by 10 of its 17 known satellites. 'So there are mechanisms at play that we don't fully understand. 'When it comes to small bodies-dwarf planets and moons-planetary scientists previously have found evidence of oceans in several unlikely places, including the dwarf planets Ceres and Pluto, and Saturn's moon Mimas,' she said. Published in the Journal of Geophysical Research: Planets, the new work could inform how a future mission might investigate the moons, but the paper also has implications that go beyond Uranus, said lead author Julie Castillo-Rogez of NASA's Jet Propulsion Laboratory in Southern California. In preparation for such a mission, planetary scientists are focusing on the ice giant to bolster their knowledge about the mysterious Uranus system.

The National Academies' 2023 Planetary Science and Astrobiology Decadal Survey prioritized exploring Uranus. The other moons had previously been widely considered too small to retain the heat necessary to keep an internal ocean from freezing, especially because heating created by the gravitational pull of Uranus is only a minor source of heat. Scientists have long thought that Titania, given its size, would be most likely to retain internal heat, caused by radioactive decay. In all, at least 27 moons circle Uranus, with the four largest ranging from Ariel, at 720 miles (1,160 kilometers) across, to Titania, which is 980 miles (1,580 kilometers) across.
