Eruption turned Mars – Dni.Ru

French scientists have made a unique discovery in time of Mars simulation. As it turned out, about 3.5 billion years ago the Red planet’s axis shifted by a quarter as a result of powerful volcanic eruption. This event could lead to the loss of the planet’s atmosphere.

as stated in an article published in the journal of Nature, experts from the University of Paris-Saclay in Orsay (France) conducted a computer simulation of the development of the Tharsis plateau, whose diameter is about five thousand kilometers thick – about 12 kilometers, and weight – about a billion billion tons. Warning scientists attracted a network of river beds far from the plateau, once flowing into the ocean , which covered the northern hemisphere of the Red Planet.

According to the researchers, 3.5 billion years ago these rivers have been flowing through the Tharsis, and not from the bottom up, and vice versa . This led scientists to believe that the largest geological structure of Mars and its volcanoes may have formed already after the Red Planet river dried up.

The emergence of Tharsis, whose mass is only 70 times smaller than the Moon , was to radically reconstruct the topography of Mars and cause large-scale changes in his appearance, completely hiding what looked like the Red planet in the past. Using computer modeling, scientists were able to determine that the Mars’ axis was shifted by 20-25 degrees after the appearance of Tharsis , with the result that the former tropics and the equator of the Red Planet have been displaced in the southern hemisphere, and its pole “moved “in the temperate regions.

“To be more precise, in fact, moved not the axis of the planet, and its crust and mantle, which literally” turned “around the core of Mars under the weight of” hump “Tharsis. This rotation axis explains several mysteries of Mars – why water reserves are concentrated not on the poles, and in the temperate zones of the Southern and Northern hemispheres, then, why the Martian rivers are located in a narrow band in the “tropics” in the southern hemisphere, and why Tharsis is located on the equator “- says one of the study’s authors Francois costar from the university-Saclay in Paris in Orsay

According to the scientists, the appearance of a volcanic plateau Tharsis, where the highest mountain of the solar system, a volcano Olympus, has led to. the fact that the axis of Mars literally shifted 20-25 degrees about 3.5 billion years ago, and its crust and mantle began to revolve around the nucleus.
