Researchers found large reserves of nitrogen on comet Churyumov – Gerasimenko. Previously, their calculations, according to which the ratio of nitrogen to carbon in comets should be approximately the same, were not confirmed.
Researchers found in the comet Churyumov-Gerasimenko reserves of ammonium salts – compounds of ammonia, hydrogen and acids. According to their theory, elements participated in the formation of molecules on Earth. They were able to draw these conclusions after analyzing the comet using the Rosetta apparatus of the European Space Agency. An article by scientists can be found in the scientific journal Science.
Our solar system formed as a result of the condensation of a gaseous cloud, known as the solar nebula. Scientists have long believed that the ratio of nitrogen to carbon in comets, which are formed in the cold outer stream of the solar nebula far from the Sun, should be approximately the same.
However, until now, scientists studying comets have seen that there was less nitrogen on celestial bodies than they expected. Researchers did not know where the “missing” nitrogen could be located and why the ratio did not match their calculations.
The first data from the instruments showed that the missing substance is hidden in structures whose existence could not be clearly explained by scientists. Having studied the location of the absorption and emission lines in these spectra, planetologists suggested that nitrogen is in ammonium salts.
Now scientists suggest that the isotopic and chemical composition of comet Churyumov – Gerasimenko suggests that components can be present in the bowels of such celestial bodies, due to which life can form. They could get to the planet after the fall of asteroids or comets.
