Saturn's satellite "Titan" has all the environments in which it is possible to investigate whether life occurs naturally from inorganic matter

Survey and research by NASA and other space development agencies on the existence of extraterrestrial life forms are proceeding. From the data collected by Cassini of Saturn's spacecraft, it turned out that there is a life enviable environment in Saturn's sixth satellite "Titan".

Saturn's largest satellite "Titan" is a satellite with unusual characteristics in the solar system. For example, "There is a huge lake on the ground and it is filled with high-purity liquid methane and ethane." "The atmospheric pressure on the ground is very similar to the earth due to the thick atmosphere layer" "The temperature is minus 180 degrees Celsius It is low ". Also, except for the Earth, Titan is the only star in the solar system where rain falls on the surface and liquid exists.

The question of whether extra-terrestrial organisms exist in Titans with the unusual circumstances as described above have bothered the cosmic biologist for a long time. However, in recent years, according to the data collected by Cassini, it is possible that hydrogen cyanide, which constitutes the major part of Titan's atmosphere, binds to other molecules existing on the ground and can form a polymer (polymer) such as polyimine It turned out. In the research we used quantum mechanics calculations, "Polyimine has electrons and it is very low temperature of organismsSpontaneous occurrenceThere is a potential to promote ".

This paper is published in the scientific journal "Proceedings of the National Academy of Sciences". Writer of the paper says that the possibility that polyimine promotes the natural occurrence of living things is highly speculative and it seems that it is like a sign of something like a structure "Polyimine can not be formed in warm places where water and oxygen exist, so only in the Titan exploration mission to be implemented in the future," Natural chemistry can develop a complicated structure chemically under all circumstances " "The hypothesis will be verified," he said.
