NASA experts suspect the existence of the ancient ocean at Charon, Pluto's satellite

Photos of Pluto and Charon we all saw. There is no doubt that these are frozen (though far from dead) worlds, with a large amount of ice of various types on and below its surface. At the same time, Charon has some oddities - his surface is dotted with a large number of huge cracks and splits. All of them apparently appeared long ago, but what is their nature?

According to some NASA scientists , Charon could have a subsurface ocean in the distant past. Over time, he gradually gave off heat, cooled, and eventually froze. Freezing, a huge mass of water expanded and destroyed the surface of Charon, which existed at the same volume of the ocean. As a result, today we can see huge cracks on the surface of a planetoid, the depth of which reaches 6.5 kilometers.

Scientists compare the situation with what happened to Bruce Benner, when he turned into the Hulk - clothes cracked at the seams and collapsed (although for some reason the pants always remained intact in the belt). Being formed, Charon gradually heated up due to the decay of radioactive elements, water ice melted, forming the subsurface ocean. As mentioned above, Charon cooled over time, the ocean froze and expanded, raising the surface of Charon.

The picture shows a part of the Serenity Chasma formation, a portion of the equatorial fault of Charon.

The lower part of the right side of the image is the topographical coloring of the photo, where green is “sea level”. Scientists believe that just the lower layers are water ice, which was once a liquid that has frozen over time. The real size of the photographed area is 386 kilometers by 175 kilometers. The picture was taken from a distance of 78700 km from the surface of Charon.
