Scientists found out that 4 billion years ago the atmosphere of Mars comprised the large amount of oxygen. The oxygen is comparable to its share on young Earth, having analyzed a chemical composition of the extremely ancient breeds in Gusev’s crater on the Mars. By the words of Bernard Wood from the Oxford university breeds in a crater contained more oxygen, than particles of meteorites, despite their identical origin. It surprised us as young meteorites. They are only 180-1400 million years, and breeds in Gusev’s crater which were studied by Spirit, were created 3,7 billion years ago. Most likely, minerals in the bottom layers of a lithosphere of Mars store in themselves the oxygen absorbed in them when they contacted to the atmosphere of a young Red planet. Wood and his colleagues found out that in the ancient time there was rather big share oxygen on Mars atmosphere and subsoil.
Herschel Space Observatory’s large telescope could find the first confirmed finding of oxygen molecules in space. The molecules were discovered in the Orion star forming complex. According to astronomers the oxygen detected by Herschel in the Orion nebula was formed after starlight warmed the icy grains, releasing water, which was converted into oxygen molecules and this explains where some of the oxygen might be hiding.
