The asteroid Benne is believed to be made of tile BLE fragments from the body 4.5 billion years ago, which contains materials generated beyond Saturn, which is a separate object long ago. Destroyed by a collision. In two new papers, scientists include amino acids (including 14 out of 20 used in land biology), polygan aromatic hydrocarbons, ammonia and other compounds, and sodium carbonate, phosphate. It is reported to detect salt such as sulfate, sulfate, sulfate, and sulfate sulfate. Chloride is a Bennu sample delivered to the earth by NASA's OSIRIS-REX spacecraft in 2023.

Dr. Nicky Fox, a semi -manager of the NASA headquarters science mission director, states:
“Asteroids provide time capsules to the history of our hometown planet, and Bennne's sample is extremely important to understand what our solar components exist before life begins on the earth.”
In the Bennu sample, researchers Found Amino Acid -Life on the Earth Used to produce proteins, 14- and all five nuclear foundations used by life on the earth, including a method of placing amino acids amino acids. Used to save and send genetic instructions to molecules. protein.
In addition, the very high existence of ammonia was detected. This is important for biology because it may react with formaldehyde detected in samples, form complex molecules such as amino acids and react in consideration of proper conditions.
When the amino acid is linked to a long chain, protein is created and almost all biological functions supply power.
These building blocks detected by the Bennu sample have previously been found on the outer rocks.
However, it supports the idea that identifying them with an unbalanced sample collected in the universe may be an important cause for the life of the entire solar system. I am.
Dr. Dany Gravin, a senior sample scientist at NASA's Godde Space Flight Center, states:
“That's why some of these new discoveries are not possible without sample return missions, close pollution control measures, and the precious curation and storage of this precious material from Benne.”

scientist It will be identified The traces of 11 salt minerals in the bene sample, which are formed as water containing dissolved salt, evaporate for a long period of time, leaving salt as solid crystals.
Similar salt water is detected or proposed throughout the solar system, including Dwarf Planet Ceres and Saturn's Moon Enkelladus.
“The discovery of these salt was a break -through in space research,” said Dr. Nick Timms, a researcher at Curtin University.
“I was surprised to identify the mineral haright, which is a sodium chloride. It is exactly the same salt as the salt that may be placed in the chip.”
“The mineral we discovered is formed from the evaporation of salt water, which is a bit similar to the salt sediment formed in Australia and the salt lake around the world.”
“By comparing with the mineral sequence of the salt lake on the earth, we can begin to imagine what the asteroid Bennne was, and provide instructions on ancient universe water activities.”
“OSIRIS-REX was a very successful mission,” said Dr. Jason Dworkin, the scientist of OSIRIS-REX, a researcher of NASA's Goddard Space Flight Center.
“OSIRIS-REX data adds a major brush stroke to photos of the solar system that may have life.”
“Why are we so far, not only to see the life on the earth, but it's a really appetite question.”
The survey results are displayed in two journals Natural astronomy And journal Nature。
