Meteors contain basic components of life

Scientific experts have discovered many chemicals similar to the main components of DNA in more than 10 meteorite samples. This is the most authentic evidence that shows that humans can be aliens who fall to Earth.

One of the extremely rare chemicals discovered on Earth, which is actually made up of space collisions or due to previous speculations, is that it is caused by the pollution. out.

Dr. Michael Callahan, lead author of the study, a chemical analyst from NASA's Goddard Space Flight Center, said that all research results show that when hitting the Earth In the early days of formation, meteorites and comets seem to have left some very important ingredients, and the chemicals found are all from outer space.

This meteorite was found in Antarctica and named Nunataks Lonewolf 94102 , containing spatial nucleobases.

He and his colleagues have published the latest findings on the Proceedings of the National Academy of Sciences on 8/8 last.

Researchers have discovered other atmospheric biological molecules in meteorite samples, among them amino acids, which help form proteins. This new study replaces two small samples of genes, called nuclear bases (nucleobases ) , compounds used to store information in RNA and AND molecules. This is also an important ingredient for human life, similar to amino acid, Mr. Callahan stressed.

To elucidate the hypotheses, Callahan's team investigated the chemical composition of 12 meteorites, of which nine were taken from Antarctic ice sheets. 11 meteorite samples contain at least one type of nucleobase, adenine, a very common ingredient on Earth.

There are also other components like exotic. Two of the 12 meteorites are Murchison and Lonewolf Nunataks 94102 which contain a lot of nucleobases , including 3 very rare species on Earth. These nucleobases belong to the purine group.

The researchers conducted a thorough analysis of meteorite samples. And surprisingly, scientists only found nucleobase in meteorite samples without being found elsewhere.

To find out how these chemicals were formed, scientists mixed the mixture including hydrogen cyanide gas, ammonia and water, the main components of meteorites in the laboratory. The results of chemical reactions are similar to those of nucleobases in meteorites. Now, Mr. Callahan is looking to continue research to see if nucleobase can be detected in other meteorites.

Also in another study published in the National Journal of Science, a group of NASA Ames Research Center leaders led by Professor George Cooper discovered chemicals such as pyruvic acid and citric acid. in some meteorites, including Murchison meteorite. On Earth, these substances play an important role in the citric acid cycle, the final cycle of degeneration of all compounds in the body.

Both of these articles have confirmed that life on Earth originated from the universe.
