Artistic impression of the interior of Saturn’s moon Enceladus, showing the interactions between native water and rock at the bottom of its ocean.
On Saturn’s moon Enceladus, there must be underground sources for which we know of only one equivalent in space so far: the "Lost City" in the depths of the mid-Atlantic, planet Earth
At a depth of 800 meters, in the middle of the Atlantic Ocean, there is a world that does not seem earthly at all – but which scientists nevertheless like to call the "Laboratory of life" designate. In the "Lost City", Discovered only in 2000, about 30 female limestone rocks, between 30 and 60 meters high, rise from the bottom of the ocean. They were formed because here rocks of the earth’s mantle come to the ocean bottom. They are made of peridotite, which reacts with seawater in an exothermic process.
