Researchers at the University of California and the Massachusetts Institute of Technology have discovered evidence that Pluto has a hidden ocean. It is tucked beneath the frozen surface area in the shape of a heart. Region Tombaugh was named in honor of the discoverer of Pluto. It has a diameter of two thousand kilometers, and experts believe that there is as much water as is in the oceans on Earth. Outdoor tank on Pluto, which is likely to be completed by the melted ice, is about 150-200 km beneath the frozen surface of the planet. As stated by Francis Nimmo of the Studies show that the environment on Pluto is more varied than previously thought – said Richard Binzel of the Massachusetts Institute of Technology.
