Water on the moon may have come from Earth

Water on the moon may have come from Earth

A NASA spacecraft, and a review of samples of the Apollo missions, have confirmed that the surface and the interior of the moon actually contains an abundant amount of water. The origin of the liquid element has been hard among scientists, who do not come to a logical explanation for the existence of the essential complement to the life in this planet debate, and how it is happened. A new study by U.S. researchers in the journal “Science” suggests that water is originating in the same meteorite that once fell on the ground.

The moon was created following the collision of a giant object against the earth there are 4500 million years ago, causing a debris disk from which the sun would have been formed. The tremendous heat of the impact would have caused the boil in the space of hydrogen and other elements, ensuring that the moon continues his training, although completely dry.

However, the new study conducted by researchers do not agree with this hypothesis. For their part, scientists at Brown University have observed inclusions from a merger, miniscule pieces of volcanic glass trapped in the crystal, so they do not share at all the case previously cited.

These melt inclusions contain a lot of water, just like the lava forming terrestrial ocean. By analyzing the isotopic composition of hydrogen embedded in the inclusions, Saal and his colleagues found that the deuterium-hydrogen is relatively low and similar to the proportion found in carbonaceous chondrites: meteorites from the asteroid belt near Jupiter, which explains the origin of water on the Moon is indeed in primitive meteorites and comets, not because they have an isotopic fingerprint, completely different.

An interesting research has shown that up to 98% of the water on the surface of the earth comes from primitive meteorites have collided against the world, confirming the presence of liquid on the planet too. According to Alberto Saal, a professor of geological sciences at Brown University and author of the study:

The simplest explanation of what we have seen is that there was water in the proto -Earth at the time of greatest impact. A portion of this water survived the impact, hence its presence on the moon. Somehow, water was not lost on impact, but I do not know what was the process that this operation had to take for this result.
