For many years it was believed that Water on Earth He even arrived at our planet in diapers through a clash Hydrogen -loaded asteroidsRecall that the water molecule consists of Two hydrogen atoms and one oxygen. The origin of oxygen is much clearer, but it was not very good where the hydrogen came from. The hypothesis of asteroids seemed to make sense, so it was preserved over time. Now, however, a study, fresh scientists from Oxford University This shows that we were mistaken with this statement.
And when analyzing a composition meteorite, very similar to what has Primitive land, They found hydrogen in completely unexpected places. This is not the first time that the meteorite is analyzed, discovered in 2012 in the Antarctic. Another analysis has already confirmed the presence of hydrogen. However, when they were in places very subject to the environment, it was believed that this could be Pollution caused by the hydrogen of the Earth.
Now, on the other hand, we know no. There is a lot of hydrogen in Much more inaccessible and primitive meteorite areasThe field as much as the necessary parts for Water formation on EarthThe field is no doubt, this is a conclusion that changes what scientific books say. This will not be a search for new information that confirms it, but the results are already considered especially solid.
Hydrogen that gave rise to water on Earth
Meteorite LAR 12252Found in Antarctica in 2012, is Condrita de EstatitaThis field is called stone blocks that gave rise to the Earth and, therefore, have the same composition as at their dawn.
From their conclusion, many scientists wanted to study it. All Estatita air conditioners are very attractive for science, and this will not be an exception. The first to find some hydrogen in their composition were French researchers. However, the investigation was incomplete.
In their case, they saw this element in the organic materials of the meteorite and Non -rustal parts of the extendedThere are the latter fields Millimeter spheres which are in the facility. Its non -tripal regions are affordable places for pollution of the Earth, since they are not necessarily part of this type of initial seeds that gave rise to a meteorite. For this, hydrogen was supposed to be found in Meteorite matrix. For this reason, this study did not serve to contradict the hypothesis that the origin of water on Earth was associated with the influence of asteroids.
The same place, different methods
The authors of the University of Oxford wanted to focus on the same moments in which their predecessors had already discovered hydrogen. The only difference is that they wanted to conduct a more thorough analysis using accurate methods such as Spectroscopy of the structure of absorption near the edge of X -Ray (Xanes)The field is a test that is held in Sinhtronfor which they chose Source of diamond in HarwellOxfordshire.
Suspected that they could find more hydrogen attached to the sulfur atoms to form Hydrogen sulfideThe field is therefore they turned all their attention to this element. But what they found was far beyond what was expected. And, accidentally analyzing the material located outside of one of the Connuls, consisting of an extremely thin material matrix, they found that the matrix itself was incredibly rich in hydrogen. In fact, there were five times more hydrogen than in non -tripal regions. This crystalline matrix formed when he made a meteorite. Therefore, hydrogen Was there from the very beginningThe water field may have needed a little more time, but the ingredients were supplied for formation.
How about polluted areas?
To eliminate any suspicions of pollution, these scientists also analyzed the areas that can be polluted after their arrival. For example, a case Cracks or oxide surfaceswhich can come only from our planet. There were practically no hydrogen sulfide in these places.
Therefore, the origin of water on Earth seems to be very different from what we thought. Hydrogen has always been there. There was no need to bring him to him.
