Oceans may be dwelling in some of our solar system’s unlikely spots.
to believe that it is the most likely satellite to retain internal heat that is caused by radioactive decay. Uranus’ other moons were believed to be too small to retain the head that is necessary to keep an internal ocean from freezing since the heating created by Uranus’ gravitational pull is only a minor source of heat.uses data from the Voyager 2 spacecraft and some new computer modeling looked at all of the planet’s five large moons: Ariel, Umbriel, Titania, Oberon, and Miranda.
New modeling shows that there likely is an ocean layer in four of Uranus’ major moons: Ariel, Umbriel, Titania, and Oberon. Salty – or briny – oceans lie under the ice and atop layers of water-rich rock and dry rock. Miranda is too small to retain enough heat for an ocean layer. CREDITS: NASA/JPL-Caltech
“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,” co-author and planetary scientist at NASA’s Jet Propulsion Laboratory Julie Castillo-Rogez. “So there are mechanisms at play that we don’t fully understand.
