The hypothesis that life on Earth may have a cosmic origin, was confirmed in studies by Russian scientists of the meteorite fragments. In these organisms, whose age is more than four billion years old were found. At this time, our Earth first formed, so to say, that at that time the microorganisms have been on the planet correctly, that is, they were introduced to us from outer space, and look for their “home” should be only in space. But there remains a major unresolved question – where exactly to look. This question has long been struggling astrobiologists all over the world.

«Not the planet, and, say, there were some bodies that had puddles, lakes, rivers, shallow seas, and lived there, these things’ – shared his thoughts Academician Alexei Rozanov, director of the Paleontological Institute of the Russian Academy of Sciences Borisyak

Inside the meteorite under an electron microscope, scientists discovered protozoa.. When Academician Rozanov presented his fotodokazatelstva, doubts about the existence of extraterrestrial life have disappeared without leaving a trace.

The bacteria can travel cosmic distances inside comets, while in a frozen state. This was confirmed by experiments in Antarctica, in permafrost and in the open space (micro-organisms have been found in cosmic dust settled on the ISS trim), although earlier it was believed that radiation and temperature extremes are harmful to all living things.

Samples Space dust were tested in the laboratory and compared with terrestrial samples. It turned out that in Earth orbit, there are the so-called extreme bacteria that live in the world in geothermal sources and even volcanic lava.

According to the academician Rozanov and his colleagues, the Earth was “seeded” by microorganisms as a result of massive bombardment comets still at an early stage of its development. Organisms from the weathering crust are older than 2.5 billion years. This suggests that the land was inhabited by organisms as soon as it was formed

Meanwhile, European astrophysicists also discovered evidence of cosmic origin of life. In a gas cloud, which is located in the center of our galaxy (26 thousand light years from our planet), special molecules that are part of the DNA were found.
