Life on Moon Titan possible - Signs of Aliens on the surface




Since Saturn and its satellites orbiting well outside the habitable zone, the emergence of life is unlikely precursors are not excluded. Overall, despite the low temperatures for the cosmochemistry very interesting events on this moon to suspect, perhaps even a kind of precursors for chemical evolution. Due to the dense atmosphere of nitrogen and organic compounds it is an important research subject of exobiology, since these conditions were the same on the early earth could. A prebiotic evolution towards life, comparable to the earth, would prevent the surface temperatures, however.
Steven Benner of the University of Florida believes that life could form in lakes of liquid hydrocarbons such as methane or ethane, since these are also suitable as solvents for chemical reactions that occur in living organisms. The chemical aggressiveness of these hydrocarbons was also lower than that of water. This would make giant molecules such as DNA, stable.
Maintains a team of researchers from France, it's possible that could use the methane lakes microscopic organisms, the energy is released when hydrogen and ethyne (acetylene) responded.
The discovery of the Cassini space probe that acetylene and hydrogen content of the atmosphere is very low, researchersassume that these gases are absorbed by or at the surface. As a cause besides chemical processes would also questioned creatures who live by these substances and change it into methane
