Comet Churyumov-Gerasimenko (67P) has a molecular oxygen. This conclusion was made by scientists after analyzing the data of the mass spectrometer ROSINA-DFMS, installed on board the spacecraft Rosetta. Data were collected from September 2014 to March 2015.
The ratio of molecular oxygen and water allowed the scientists to conclude that they have the same source – the substance of the nucleus of the comet, evaporating under the influence of the sun. This proves that the “original” material from which the solar system was formed, was in the structure of the molecule of oxygen.
Scientists say today’s models of formation of the solar system can not be explained by the presence of oxygen on the comet. Up to this point in the clouds of dust and gas surrounding the comet’s nucleus, they found water, carbon monoxide and carbon dioxide gases. Comet Churyumov-Gerasimenko was the first space object containing oxygen molecules.
Rosetta spacecraft was launched to the comet Churyumov-Gerasimenko in 2004. On board was landing module Philae (Fila). Last year, the unit has reached its target. Completing the mission will take place in September 2016. Rosetta, approaching the comet to fall on its surface.
As astronomers believe the comet Churyumov-Gerasimenko was formed as a result of a collision between two space objects consisting of rock and ice.
