Nizak from Alaska challenge the theory of how the land got its waters

Water is necessary for life as we know it, but scientists are still not sure how it was established on Earth. One theory is that the asteroids that express the American hydrogen, are necessary to form water molecules, through collision with our planet in its early history. However, a new research indicates that the Earth has already has enough hydrogen on its own, thank you very much.

The UK researchers have discovered unknown quantities of hydrogen in a type of meteorite called ENSTATITITETITITITERITE. I know what you think: What is the relationship of hydrogen in the meteorite with the origin of the water on the ground? The formation of EntaTite Chondrite is closely like the Earth’s process 4.55 billion years ago. So if the meteorite has its source of hydrogen, it is likely that the early land is also, which means that the water could be produced without the help of foreign envoys.

“The main question for planetary scientists is how the Earth has become as it does today. We now believe that the materials that were built our planet – which we can study using this rare meteorite – were richer in hydrogen than we thought previously.” statement. “This discovery supports the idea that the formation of water on Earth was a natural process, rather than a waterproofing asteroid bombing our planet after its formation.”

Praison, co -author on Ticket It was published earlier this month in Icarus, and his colleagues in EntaTite Chondrite achieved Alaska known as Lar 12252. Ticket From the same meteorite, it has already found traces of hydrogen, and these effects may have caused ground pollution, according to the statement.

Scientists have speculated that LA 12252 may host large quantities of “original” hydrogen associated with sulfur. As a result, they used an intense ray of X -rays to search in the meteorite for sulfur compounds. While studying the matter, he called MatrixSurrounding one of the cartilage (small spherical ingredients), the team hit the Grand Prix: hydrogen sulfide. They discovered that the entire matrix has large quantities of the compound, which reaches five times hydrogen as it is in the non -crystal parts of cartilage in the meteor, where the previous study has already discovered the effects of hydrogen.

Miscellaneous, parts of the meteorite that clearly witnessed ground pollution, such as rust, had little or non -hydrogen. This means that hydrogen sulfide in the matrix is ​​likely essential. Since the meteorite composition is similar to that of 4.55 billion years, this indicates that by the time the Earth was exposed to asteroids, it could have enough hydrogen to produce the amount of water in the end of our planet today, according to researchers.

“We were incredibly excited when the analysis told us that the sample contains hydrogen sulfide – not only as we expected,” said Tom Barrett, the lead author of the study and a scientist of the Earth Sciences Department at Oxford University. “Since the possibility that the hydrogen sulfide that arises from Earth pollution is very low, this research provides vital evidence to support the theory that water on Earth is original – a natural result of what our planet makes.”

Water is necessary for all known living creatures. As such, by providing a new vision on how the Earth gets its water, the study also sheds light on the mystery of life on our planet.
