Scientists from Samara National Research University named after academician S.P. Queen for the first time
We're talking about small solidshydrocarbon particles containing PAHs, they are also called interstellar grains: in fact, they act as molecular cosmic factories for the synthesis of organic matter, for example, amino acids or sugars.
According to scientists, grains with such molecules move through space, sometimes find themselves in favorable conditions, where, on their basis, the origin of life is possible.
The reaction we have described occurs between a moleculestyrene and methylidine radical. The result is an intermediate state, which cyclizes and subsequently leads to the formation of aromatic indene and atomic hydrogen.

At the moment, there are no alternatives to the described mechanism of indene formation in space.
The carried out astrochemical modeling of the proposed reaction fully confirmed its possibility in space conditions.
