Pluto has a buried ocean. If there's a water source in this dwarf planet at the outskirts of our solar system, then that might mean there is a possibility that other planets, exoplanets, and worlds in the universe are also hiding oceans underneath their surface.
A gassy insulating layer probably keeps Pluto's liquid-water ocean from freezing solid, a new study reports. And something similar could be happening under the surfaces of frigid worlds in other solar systems as well, study team members said.
"This could mean there are more oceans in the universe than previously thought, making the existence of extraterrestrial life more plausible," lead author Shunichi Kamata, of Hokkaido University in Japan, said in a statement.
