Experts have discovered bacteria that live at a depth of 19 km underground. It is possible that this is the most underground type of life on our planet. For biologists, the study of these bacteria is crucial value. By studying these microorganisms, scientists will be able to understand the possibility of the origin and development of life on other planets, the soil and whose climate is significantly different from Earth. Earlier researchers believed that microbial life in the earth’s crust could be only possible at a depth of several kilometers. Now now ideas about the degree of the Earth’s biosphere have expanded significantly. On the For several decades, specialists have studied rocks on Territory Lopez Island (Washington, USA). In the end they found in stones recovered as a result of geological processes on the earth’s surface tens of millions of years ago, veins, containing the mineral aragonite, which is highly saturated with isotopes carbon. This carbon is formed as a result of life. microbes that secrete a gas containing a methane compound. A likely explanation for chemical changes in carbon is that millions of years ago deep in the earth’s crust were some life forms are buried. Since the microbes were very deep underground, they were subject to extreme temperatures and pressures, which, in turn, demonstrates to scientists the possibility microorganisms adapt to the harshest life conditions and also bode well for development life beyond our planet. Scientists believe the more they learn about the extreme living conditions of organisms on Earth, the more will understand if life in other worlds is possible. About 100 million years back due to geological processes on the surface of the earth stones from basalt were at a great depth in the bowels of the planet. Subjected to extreme temperatures and pressures, stones became thin, whitish veins of aragonite are created, and as a result bacteria began to release methane, which changed chemical composition of carbon. However, how could microorganisms survive at a temperature exceeding 120 ° C and at atmospheric pressure 5000 times stronger than above sea level? Scientists believe that it is the close proximity to groundwater made it possible the existence of life in such unacceptable conditions. Moreover, paradoxically, but, the fact that extremely high pressure on the in fact, it can stabilize the structure of biomolecules, such as like DNA, compensating for the devastating effects of huge temperatures. Similar scenarios for the development of life are still preserved by to the whole world today, that is, the biosphere of the Earth can be extended by many kilometers inland from the surface of the planet. Because if 100 million years ago, the life of microorganisms deep under land, flourished, most likely, similar microbes live there and today. The results of studies have shown that life can exist in an incredible variety of ecosystems. A similar approach can be applied to unearthly life forms, which possibly exist on planets like Mars.
