Energy particles released by satellites suggest that oceans exist.
Perhaps one or two moons on Earth's Uranus have underground oceans, according to scientists based on data obtained by the Voyager 2 spacecraft back in 1986.
Voyager 2 is the only Earth spacecraft to pass by Uranus. During the flyby, the spacecraft discovered that one or two moons of Uranus emit characteristic energy particles.
The presence of such particles is usually "a spokesman for the discovery of the ocean world," according to cosmologist Jan Cohen of the Johns Hopkins Applied Physics Laboratory. Scientists believe that liquid oceans are hiding under the ice.
The researchers' findings will not be confirmed or refuted until after the 2030s. This will require a special mission to Uranus. NASA has already planned a mission, but it will begin as soon as that.
Researchers will continue to analyze the Voyager 2 data until the end of the year. Scientists now believe that oceans are most likely to be found on one of Uranus' two moons, Miranda or Ariel.
