A team of Russian Samara University scientists described, for the first time, the process of the emergence of an organic molecule in space, which plays an important role in the chemical development of the universe.

And Science Advances notes that, according to the scientists, the data they obtained expand upon the perceptions of the emergence of life and explain how “interstellar factories” work in the synthesis of organic materials.
According to experts’ estimates, about three million tons of interstellar dust, consisting of minerals and complex organic materials, that is, carbohydrates and their derivatives, fall on Earth annually.
The scientists point out that the processes leading to the formation of organic compounds in space have not been sufficiently studied yet. These processes are characterized by the absence of effective external energy sources, which makes them very rare and requires special components. On Earth, these processes happen simply thanks to the presence of different chemical compounds and the possibility of obtaining energy in the surrounding medium.
The new study, conducted by Samara University scientists, in collaboration with specialists from the University of Hawaii in Manoa, Florida International University, and Benedictine College in Atchison (United States), shows for the first time how the simplest polycyclic aromatic hydrocarbon (PAH) indin can form without any hindrance. At temperatures that correspond to the conditions of space.

University researcher Galia Galimova says, “Solid hydrocarbon molecules containing PAHs are usually called interstellar grains, which actually act as a plant to synthesize organic matter, such as amino acids or sugars. The initial steps that we have identified leading to the formation of aromatic hydrocarbons. Polycyclic in space, essential for understanding the chemistry of the carbon material in our galaxy. “
The researchers suggest that small inorganic particles on the surface of interstellar grains can interact with each other, forming a chemical “assembly” of more complex biological molecules. These particles move in the interstellar space until suitable conditions for the birth of life appear. According to experts.
“The process that we described takes place between the sterol molecules and the methylidine root, which results in an intermediate state, which in turn turns into aromatic indene and atomic hydrogen,” Galimova says.
The researchers announced their intention to continue research in this area in the future.
