Water with comet Churyumov-Gerasimenko in composition different from that which exists in the world, according to the online European Space Agency (ESA). So, do not confirm the theory that water on Earth was the result of falling comets.
Scientists reported that the proportion of heavy hydrogen, or deuterium, composed of water vapor on the comet is much higher than its share of the water on Earth. “It’s probably exclude the fact that the water in the world was the result of a comet” – the newspaper The New York Times statement collaborators, University of Bern in Switzerland Catherine Altwegg, which is engaged in research data.
According Altwegg is more likely that the water brought to Earth asteroids and comets are not, according to RIA “Novosti” with reference to agency AFP. So far, none of the theories do not prove the truth – the question of the origin of water on Earth is still open.
The data have been analyzed by scientists obtained device ROSINA, mounted on the probe Rosetta. It was reported earlier that the specialists do the study of organic molecules from the comet Churyumov-Gerasimenko.
Module Philae probe Rosetta for the first time in the history of landed on the three-kilometer nucleus of a comet Churyumov-Gerasimenko, November 12 and then began to study the chemical composition of the comet’s nucleus.
