An article published in the journal “Nature Geoscience” reports the results of a study of the conditions that could allow the presence of an ocean below the dwarf planet Pluto’s surface. A team of researchers analyzed using computer simulations the possibility that under the heart-shaped area called Sputnik Planitia there’s a layer of gas hydrate of the class known as clathrates formed by water and natural gas which acts as an insulator allowing the layer below them it remains warm enough to keep water in its liquid state.
