Antarctica opened an ice mystery

Russian scientists have discovered a unique organism, which disappeared in the subglacial lake Vostok in Antarctica. A bacterium similar to the famous science of living beings is only 86 percent.

Age is estimated by scientists of the East in 20 thousand years, the lake is completely isolated from the outside world for 15 million years. In the upper part the water temperature is minus two or three degrees Celsius at a pressure that exceeds atmospheric to 400 times. Scientists suggest that at depth is geothermal, the hot water thus it can develop microorganisms. Another interesting feature of the East can be called that the oxygen content in a hundred time higher than it usually happens in the water.

A unique microorganism found in the borehole 5G-1, which in 1989 together began to develop the Soviet, American, and French scientists. The surface the researchers reached in 2015. They are brought to the surface two ice roll with depth 3767,57 meters. It is in the frozen on the drilling crown water found an unknown bacteria, which is called the w123-10. According to the head of the laboratory of cryostability Petersburg nuclear physics Institute named after Boris Konstantinov genetics Sergei Bulat, probably being w123-10 became the second bacterium, discovered during the drilling of lake Vostok. First discovered by Russian and French scientists on the deep and 3561 3607 meters. The depth of separated layer of ice age-five thousand years. Being Hydrogenophilaceae thermoluteolus quite comfortable lives at temperatures around minus 50 degrees Celsius.

If life really is in lake Vostok, it is a kind. Roughly such conditions, scientists believe that ice exists in the oceans of the moons of Jupiter, Saturn at the poles of Mars. Therefore, the study lakes of Antarctica allows the astrobiologists on Earth to learn about potential life in the cold worlds in our Solar system.
