– But the losses are much less than expected. It is apparently that it is very cold in the upper part of the atmosphere, says Johansen.
The researchers suggest that the extreme cold must depend on an unknown factor.
another interesting detail is that Pluto is surrounded by a blue-colored fog that seems to consist of several layers.
– the fog is made up of tiny particles, called toliner says Johansen.
the surface of Pluto consists partly of mountainous areas. But an enormous area of 870 000 square kilometers just north of the dwarf planet’s equator appears completely flat and flat.
This is probably a solid block consisting of frozen nitrogen and carbon monoxide. Johansen points out that the temperature on Pluto is around 230 degrees below zero.
– It’s a very cold celestial body, covered with exotic ice that moves in the same way as the glaciers of water ice does on Earth. There are regular water ice on Pluto, too, but it is as hard as rock on the earth because of the cold, he said.
The new findings presented in five articles in the journal Science. In the articles analyzed, except Pluto’s atmosphere, surface formations and geology of the dwarf planet and its largest moon, Charon. The researchers also examining Pluto’s four småmånar, Styx, Nix, Hydra and Cerberus.
All småmånarna is very irregular and may look like boulders or potatoes, rather than moons. Interestingly, it seems that all five men are mostly composed of regular ice.
– Pluto probably collided with a large iskropp when it was young, for about four billion years ago. Karon and the other moons are remnants of the collision, says Johansen.
