Researchers find ocean on Saturn's moon Mimas. Until now, experts assumed that the interior of the celestial body was solid.
Now researchers are deducing from ancient data that Mimas has a deep ocean. It was formed a maximum of 25 million years ago, according to the scientists in the journal Nature. The discovery is likely to change the way planetary scientists view the many small ice moons of the large planets in our solar system. There may be other large oceans hidden beneath the surfaces of some of these inconspicuous celestial bodies.
