Titan is most similar to the Earth object of the solar system, which has its own seasons. There are rivers, lakes and even seas. The only difference is that the average temperatures in this place, which is far from the sun, never exceed -180 degrees. The liquid is represented by methane and ethane – substances that exist on Earth only in the form of gases. For several decades, scientists have been seriously arguing that even the simplest life could exist on the Saturn satellite, but new studies show that despite the hopes of mankind, the giant planet's moon is uninhabited. Why did astronomers give up their dreams of finding extraterrestrial life on the most mysterious satellite in the solar system?
Is there life on Titan?
The Saturn satellite Titan is the second largest moon in the solar system after frozen Jupiter Ganymede. Despite the extremely low temperatures prevailing on the surface of the giant planet's satellite, Titan has its own dense atmosphere and even real oceans and liquid oceans, much like terrestrial gasoline. Despite this unusual form of existence, the Titanic seas could become a kind of cradle of life for extremophile organisms that can be found all over the world. With the wide range of organic ingredients that Titan is famous for, local life could gradually evolve to at least the simplest level. Most likely, the emergence of life on titanium is only possible in the bold dreams of science fiction authors, writes the scientific portal lifecience.com. The mistake in this case will be quantum mechanics and its strange rules that regulate subatomic particles.

The fact is that lipid molecules on Earth can spontaneously organize themselves into bladder membranes that form barriers around the cells of all known life forms. According to researchers, it was the formation of the first such structure that once led to the development of the first living organism on earth – the ancestor of all organic life on our planet. In the past, researchers speculated that an equivalent set of bubbles consisting of nitrogen molecules called nitrogenosomes could appear on titanium. However, in order for these unique structures to arise naturally, nature has to consider several important factors.
Previous studies that used molecular dynamics modeling as a method to study the chemistry of life have shown that it is precisely nitrogen-based bubble structures that could very well arise in a world like titanium. However, an article published in Science Advances magazine proves that all previous simulations of the occurrence of life on the Saturn satellite have been flawed.
Using more modern simulations using quantum mechanics, the researchers examined organic structures in their new work from the point of view of their "thermodynamic viability". In practice, this concept means that all chemicals tend to build their existence in a simple, energy-saving scheme. In this case, Titan’s nitrogenosomes do not fall under the concept of simple and effective “devices” for the formation of life.

Despite the fact that the creation of organic life on the giant planet's largest satellite has been officially recognized as impossible, the researchers hope to find traces of exotic forms of living matter on Titan that use principles of their fortress other than earthly. The most anticipated mission to identify this possibility is that planned for the 2030s. Dragonfly mission that may be able to discover life without the cell membrane required for living organisms on Earth.
