Experts from Yale Institute believe that extraterrestrial creatures may live literally under our feet. The researchers are convinced that they live at a depth of 19 km, where extreme temperatures and high pressure. Scientists are looking for life not only in space, but in the bowels of the Earth. Attention to our planet was drawn after you have identified special isotopes of carbon in the ancient rocks of aragonite on the American coast of Lopez island in Washington state. This has led scientists to the conclusion that the minerals originated under the influence of water, rich in methane organic origin. They are of the opinion that the underground environment is quite suitable for the existence of alien life. It turns out the crust protects the organisms from deadly cosmic radiation and elevated temperatures. "Most studies recognize the presence of bacteria on the depth, measured in kilometers," he said, geologist Philip Stoddard Business Insider. "The more we learn about extreme environments on our own planet, the more we realize how much living organisms are able to adapt to them", he added. Earlier it was reported that scientists from the Institute of Berkeley decided to look for an alien civilization on a distance of 20 light years from Earth (about 200 trillion km). Experts will choose a specific planet, where, in their opinion, may be a life, and go e-news, which, however, has not yet been developed. Approximately, there will be information about the location of the planet and description of the human species.
