In the samples taken out of the distant asteroids, scientists have discovered many organic elements, including the key foundation of life.

Surprising discovery shows that the chemical composition required for life may exist in early solar systems.

NASA's OSIRIS-REX spacecraft was launched in 2016, from a small planet Bennu and Then brought them to Earth in 2023. The 45 billion asteroid was considered formed in the first 10 million years of the solar system.

An asteroid material collected by asteroid materials published in "Nature" magazine on Wednesday shows that these samples include thousands of organic compounds, and 14 amino acids that are used on the earth for the formation of protein. The sample also contains the main components of four "nuclear bases" -DNA and RNA, which store and transmit genetic blueprints in our cells.

Researchers did not find evidence of life itself on Bennu. On the contrary, their results have enhanced such a theory, that is, the asteroids who fell into the earth when the asteroid falling into the earth may have given the elements necessary for life. These findings may also mean The opportunities for life formed by other planets and satellites in the solar system may be higher than that of scientists.

NASA Scientific Mission Bureau Deputy Manager Nicky Fox said in the news on Wednesday: "Osiris-Rex task has been rewritten textbooks, introducing our understanding of ingredients. There are necessary components in our lives in our solar system.

In the past, similar organic molecules, including amino acids, had been detected in meteorites, but the fragments of these space rocks were not perfect because they studied after experiencing a hot journey in the earth atmosphere.

Although meteorites have been exposed to the earth and polluting the conditions that may be biased towards scientific results, collecting samples directly from the asteroid in the space is like staring at a time capsule from the new solar system.

Danny Glavin, a astronomer at NASA's Goddard Space Flying Center, said: "Osiris-Rex Bennu found that these samples are primitive."

Gravin said that the return tank carrying Bennu samples to avoid harsh conditions during the atmosphere.

He said: "The most important thing is: the organic materials we see in these samples have aliens rather than pollution." "We can believe these results."

In Bennu's sample, the researchers accidentally discovered some surprises. First of all, they discovered that the exceptional ammonia- "100 times higher than the natural ammonia water found in the soil on the earth," Gravin said.

Ammonia is an important component in many biological processes, including the basis for forming amino acids, and then connects to the growth chain to generate protein.

Another surprise The second paper published in the magazine published on Wednesday described: Researchers have discovered the traces of 11 types of minerals. These minerals may be the purple mixture left after the water sinking of Bennu and their parents asteroids. Part of.

Tim McCoy, a meteorite of the Smithsonni Natural History Museum in Washington, said, said the water content of evaporating water on the earth and the crust of sodium -rich sodium (such as Caolisa Lake) The salty crystals left, such as Searles Lake, California. The author of two studies.

In a statement, McCowe said: "We now know from Bi Nu that the original ingredients of life are combined in a very interesting and complicated way." "We found the next step towards the way of life."

The detected minerals include sodium carbonate compounds, such as TRONA (sometimes called "soda ash"). Scientists have never been observed in other alien samples. It is believed that there are similar brick mixtures on Saturn's lunar natives and dwarf stars.

Two new studies represent the first in -depth analysis of the Bennu sample. In 2023, scientists announced the initial discovery of traces of carbon and water locked in clay minerals.

Bennu's soil and rock are the first samples collected by NASA and recovered from small planets, but they are not the first in history. Japan's Hayabusa mission in 2010 conveyed a few micrograms of asteroids to the earth, called iTokawa. The second time called Hayabusa2 was provided with a small sample from the small planet Ryugu in 2020.

Although Bennu's samples have produced interesting results, more research needs to be carried out to understand what accurate causes life to appear on a planet or moon rather than other planets.

"Benu has nothing to do with the earth?" Said Jason DWORKIN, the Osiris-Rex project scientist at NASA's GODDARD Space Flight Center. "For celestial biologists around the world, this is a future research field. Thinking of Bennu as a place where everything has everything but has no life. Why is the earth special?"
