A Meteorite From Alaska Challenges Theory of How Earth Got Its Water

As we know, the water for life is important, but scientists are not sure how the world is still in place. A theory is that the asteroids expressing the US hydrogen, which is important for the formation of water molecules, colliding with our planet in early history. However, the new study offers that the earth is already a fairly hydrogen, thank you very much.

Researchers in the UK called a meteorite called a meteorite of a type of hydrogen, previously unknown. I know what you think: What should hydrogen in meteorite should do with the origin of water on earth? The composition of Enstatite Chondrite meteorites is similar to earth 4.55 billion years ago. Thus, if the meteorite has its own hydrogen source, the early place is most likely to produce water without the help of foreign emissaries.

“As today is today, a basic question for planetary scientists, as today, using these rare meteorites, as today, the material we can learn from these rare meteorites,” he said. statement. “This finding supports the idea that water on earth is a natural process, more than the occurrence of a natural process, more than the formation of chopped asteroids.”

Bryson, joint author learn This month, previously published in ICARUS and examined an Enstatite Chondrite meteorite from Alaska, known as colleagues, 12252. As a previous learn The same meteorite had already found hydrogen traces, these traces may be caused by the pollution of the earth.

The scientists behind the new study think that in 12252, they can accept a large amount of “native” hydrogen for sulfur. As a result, they used a lot of rays to seek meteorite for sulfur compounds. When reading the issue, called matrixThe team jekpot covering Chondrules (from small spherical components): hydrogen sulfide. The large amounts of combination of large amounts of combinations of the whole matrix have noticed that previous investigations have already been five-time hydrogen in the summary parts of the Meteorite Chondrules.

Significantly, clearly located surface pollution, there were no hydrogen as a rust. This shows that hydrogen sulfide in the matrix is ​​most likely intrinsic. Since the composition of the meteorite is similar to the Earth’s Asteroids, this shows that today the world’s planet today shows that the planet homeowner water produces the amount of water today.

“When our analysis tells us of hydrogen sulfide samples where we tell us, we were incredibly excited,” said Tom Barrett, the author of the study and Oxford University by the Department of Land Sciences. “Because the probability of this hydrogen sulphide arising from the ground contamination of this hydrogen sulge is very low, provides vital evidence to support the theory where water on earth is the natural result of our planet.”

Water is important for all known creatures. Thus, by giving a new idea in how the earth is, the research also sheds light on the sustainable secrets of the origin of life on our planet.
