Comet Churyumov-Gerasimenko may be inhabited by alien microbes

Comet 67P/Churyumov-Gerasimenko which is travelling now in the company of the device of the probe Philae and Rosetta could be inhabited, according to The Guardian . According to scientists, testifies to this rich organic compounds black crust of the comet.

According to leading astronomers, its presence can be explained by the presence under the ice crust “of microbes-extremophiles”, able to adapt to the harshest conditions. Similar microbes surviving in extreme conditions in the most inhospitable corners of our planet.

Previously, Rosetta also found a strange accumulation of organic matter, particles reminiscent of viruses.

However, as scholars have noted, neither Rosetta nor Philae is not equipped to directly detect life – then, 15 years ago, when preparing the project, according to astronomer and astrobiology Chandra Wickramasinghe of, over such a proposal would only laugh.

He and his colleague Dr. Max Wallis from Cardiff University believe that the comet Churyumov-Gerasimenko can serve as a home for living organisms. In their opinion, that such comets could in their time to bring life to Earth.

Their study shows that germs can inhabit the areas of the comet where there is water. Organisms that contain salts that act as an antifreeze, is able to maintain activity at temperatures below 40 degrees.

The comet has a black hydrocarbon peel, ice smooth “seas” and craters with a flat bottom containing a second frozen water mixed with organic remains. According to Wickramasinghe, the data indicate that in creating the ice structures of the comet involved microorganisms. A mixture of ice and organics warms in the Sun, and it can be inhabited by microorganisms.

Previously, the information obtained c Rosetta spacecraft have allowed scientists to get an idea about the structure and temperature of the comet Churyumov-Gerasimenko. As it turned out, this comet with a double nucleus, shaped like a rubber duck the size of three by five kilometres. At the end of last year the comet was at a distance of 400 million kilometers from Earth and was traveling approximately 55 thousand kilometers per hour.

Recall, the Rosetta spacecraft was launched 11 years ago and reached its goal in August of last year. During these years, Rosetta has gone 6 400 000 000 kilometres along a very complicated path, it is five times the distance from earth to the Sun. For 11 years the unit several times changed the direction of flight to reach the target, once become acquainted with Mars and three by Earth. Rosetta also successfully overcame the asteroid belt, simultaneously exploring two asteroids, 2867 steins, 21 Lutetia. Its meeting with the comet had already made 10 the loudest and expected breakthroughs of 2014 in the world of science.
