NASA confirmed the existence in the atmosphere of Titan vinylcyanide connection, which may be a component of cell membranes in microorganisms may live in the methane oceans of Saturn’s moon. Briefly on the results of a study published in the journal Science Advances, is told in a press release on the website Phys.org.

Cell membrane from the earth’s organisms are made up of phospholipids — molecules consisting of polar (water-soluble) “head”, containing a phosphorus atom, and two non-polar tails of the fatty acids residues. Such a structure promotes the formation of elastic sheath cells. However, the hypothetical microorganisms whose livelihoods are based on methane, instead of water, the membrane must consist of other compounds, for example, vinylcyanide.

Scientists have discovered traces of vinylcyanide in the atmosphere of Titan at an altitude of 200 kilometers using a set of radio telescopes Atacama Large Millimeter Array (Chile). The greatest concentration of the molecule was achieved in the areas above the South pole of the satellite. At low temperatures (minus 179 degrees Celsius), characteristic for Titanium, vinylcyanide should concentrate in drops and fall on the methane lakes.

Simulations showed that the sea Legei in the Northern hemisphere of Titan vinylcyanide should be sufficient for the formation of 10 thousand cells per cubic centimeter. This is ten times more microorganisms than bacteria in the coastal areas of the earth’s oceans.
