Subglacial volcanoes have revived the hopes of finding life on Mars


Experts from the American space Agency NASA, found that under the ice covering the poles of Mars, billions of years ago volcanoes were erupting. This, according to scientists, could contribute to the formation of a warm environment with high humidity levels, which in turn would create quite comfortable conditions for life of microorganisms.

American experts analyzed data obtained by using multifunctional automatic interplanetary station Mars Reconnaissance Orbiter. The spectrometer, installed at this station, allowed us to understand how there was an unusual relief on the territory of one of the southern regions of the red planet, called the mountain of Sisyphus: this part of the planet’s surface is dotted with small mountains with flat tops. As a result, the specialists were able to confirm that this polar area of Mars is under ice volcanoes. Earlier such suspicions suggested similar areas on Earth, however, direct proof of this assumption were obtained for the first time, the researchers note.

According to the researchers, their discovery provides evidence in favor of the assumptions that informed the entire surface of Mars was covered with ice, which was heated due to volcanic eruptions. Eventually the ice turned into steam, which evaporated into space because of the fact that Max, in comparison with the Earth, had the rarefied atmosphere and weak gravity, according to the NASA website.

Earlier, a group of experts led by Tim Parker of the jet propulsion Laboratory of NASA in Pasadena made with a different explanation of the appearance, and then evaporating ice on Mars. According to the theory proposed by these scientists, during the “late heavy bombardment” occurred around four billion years ago, a large amount of ice on Mars has brought the asteroids. They warmed up the planet so that the ice melted and formed on the red planet, the ocean, further evaporated.
