Called the main condition for the emergence of life on the planet


Although the Land was and still is the only planet in the Universe, of life on which humanity known to scientists continues to be interested in the question, the combination of what major factors led to its formation on our planet, and perhaps elsewhere. In their new study, experts from the European space Agency announced a major prerequisite for the origin of life ultraviolet radiation.

With all the variety of forms taken by life on Earth, at the heart of it are always the same basic components — the atoms of carbon, United with hydrogen, oxygen, nitrogen and other elements. At the same time, according to experts, still there is no single answer to the question of what forced these substances to unite into compounds, which is the “blocks of life”. Still was considered the basic assumption that the molecules of the hydrocarbons formed under the influence of turbulence. But a new study put forward an alternative hypothesis — according to astrophysicists, life on Earth appeared not as a result of “shaking”, and due to the ultraviolet radiation emitted by the Sun.

Experts observed the processes occurring in the Orion Nebula, the nearest region of space where there is an active process of star formation. In particular, the experts were interested in the quantity, temperature and movement of the hydrocarbons (CH) and their ions (CH+) and carbon ions (C+). As it turned out, most of the hydrocarbon is formed in those parts of the nebula, where the emission of young stars ultraviolet radiation was more likely. According to researchers, the ultraviolet light heats the molecules of hydrogen, thereby causing it to react with carbon.

While events such as supernova explosions, which were to lead to the formation of turbulence, a significant impact on the formation of hydrocarbons is not provided, scientists say.

Their conclusions experts have shared in the journal Astrobiology.
