Stone formations on the surface of mars with amazing coincide exactly with the fossilized remains of ancient colonies microorganisms on earth. Ever since the NASA mission site Curiosity first photos appeared from the surface of Mars, each anyone can study the pictures and conduct their own research. To make sure that people’s imagination is not asleep, just type in to a search engine a phrase like: “found in photos from Mars …” However amid numerous press reports, you can find quite serious scientific research. One of them has become recently published on the pages of the scientific journal Astrobiology detailed comparison of objects in photos taken by the rover Curiosity, with terrestrial geological structures. The author of the work, geobiologist Nora Noffke made a reasonable assumption that the structure of stone formations captured by the rover, surprisingly reminiscent of various terrestrial sedimentary rocks biological origin.

These microorganisms form colonies measuring a few millimeters in size to a kilometer, which are located on stones under a small layer water. Throughout the life of such a community, a gradual mineralization of dead layers. As a result of mineralization processes Specific patterns are formed on the stones. It is these fossilized layers with their characteristic structure and serve as evidence the existence of life in those distant geological eras. In 2008 Nora Noffke found petrified in western Australia structures of biological origin 3.5 billion years old.

When Nora caught sight of photographs of Martian soil, her attention was drawn to the extreme similarity of stone formations with terrestrial fossils of ancient colonies of microorganisms that she studied for 20 years. The fact is that each kind of such bacterial settlements has its own characteristic imprint, which can say a lot about the colony itself, about the climate and about others conditions. For example, you can distinguish a colony living on the banks of a river, from colonies located in seasonally flooded areas. therefore the look of an experienced geobiologist noticed precisely the features in the structure stone martian landscape that resembled landscapes formed by living organisms. However, according to Researchers cannot completely exclude, for example, rock erosion under the influence of wind or water, which theoretically could to form a similar relief. The exact answer to this question will be able give an analysis of Martian soil samples if they ever will be delivered to Earth.

The study of the surface of the red planet, including thanks Curiosity mission, discovers all new facts about the Martian stories. There was water on Mars, as dry channels indicate rivers and lakes. Methane and some other organic molecules. All this indirectly indicates the similarities in the development of Mars and the Earth, and perhaps life was born on two planets at about the same time.
