Earth-like moon of Saturn has failed the test of the existence of extraterrestrial life

Titan — the most Earth-like object in the Solar system, which has its seasons, has its own rivers, lakes and even the sea, with the only difference that the average temperature this far from the Sun never exceed -180 degrees, and all the aforesaid liquid is represented by methane and ethane — substances that exist on Earth only in the form of gases. For several decades scientists have seriously argued about the possibility of the existence on Saturn's moon at least , but new research shows that despite all the hopes of mankind, the moon of a giant planet is uninhabited. So what has forced astronomers to abandon his dreams of finding alien life on the mysterious satellite of the Solar system?

is There life on Titan?

Saturn's moon Titan is the second largest moon in the Solar system after Ganymede of Jupiter frozen. Despite the extremely low temperatures reigning at the surface of the satellite of a giant planet, the Titan has its own dense atmosphere, and even the real seas and oceans of the liquid, its composition is close to the earth's gasoline. Despite such an unusual form of existence, the seas of Titan could become a kind of the cradle of life for organisms, the extremophiles that can be found everywhere on Earth. Using a great variety of organic ingredients, which is famous for the Titan, the local life could evolve at least to the elementary level. However, most likely, the emergence of life on Titan is possible only in the wildest dreams of science fiction writers, writes the portal . Blame, in this case, it will be quantum mechanics and its bizarre rules that govern subatomic particles.

The fact that the Earth lipid molecules can spontaneously organize themselves into vesicular membranes that form barriers around the cells of all known forms of life. It is the first such structure, according to the researchers, one led to the development of the first in the Land of the living organism — the progenitor of all on our planet. In the past, researchers have assumed that the Titan could appear equivalent to a set of bubbles consisting of molecules based on nitrogen, called astesani. However, these unique structures could arise in a natural way, nature must take into account several important factors.

most of all, organic life on Titan does not exist

Previous studies, using simulation of molecular dynamics as a method to study the chemistry of life — assumed that the bubble structure on the basis of nitrogen compounds may arise in a world like Titan. However, an article published in the journal Science Advances, proves that all earlier simulations of the emergence of life on Saturn's moon was incorrect.

With a more streamlined simulation using quantum mechanics, researchers have studied in the new work, organic structure from the point of view of their «thermodynamic viability». In practice, this concept means that all chemical substances tend to build their existence into the simplest, low-energy scheme. Astonomy Titanium in this case does not fall under the concept simple and effective “device” for the formation of life.

Despite the fact that officially recognized the impossible on the largest satellite of the giant planet, the researchers hope to find on Titan traces of exotic forms of living matter, uses of earth the principles of his pastrone. So, the most anticipated mission for the detection of this feature is planned in 2030-ies the mission of the Dragonfly, which, perhaps, will be able to discover a life without the presence of the essential living organisms of the Earth of the cell membrane.
