Origins of life in asteroids. top

Discussions about the transmission of life on earth have been going on for a long time. Many have questioned whether life on earth came from outside. The astronomical specimens made that question even stronger. The specimens contained some organic matter found on Earth that may have formed in space. Scientists have made such a claim on Friday. A Japanese space observatory collects those tiny samples of asteroids.

The original material was brought to Earth in 2020 from an asteroid named Rouge. After six years of conducting the mission, it was brought to Earth from a distance of about 300 million kilometers. Then came the experiment. Scientists studied some part of that small rock of only 5.4 grams. But in the first study of asteroid material,

A research paper by a team of researchers led by Okayama University in western Japan was published yesterday. In the research article, the scientists said that they have discovered other organic matter, including amino acids, in asteroid samples, which could be the source of life on Earth.

The study found that the discovery of protein-forming amino acids is important. Because, like the meteorite, Rouge did not come into contact with the earth's fauna. So the discovery of amino acids in Rouge suggests that the earliest sources of life on Earth may have been formed somewhere in space.

Researchers say they have found 23 types of amino acids in asteroid samples taken from Japan's Hayabusa-2 spacecraft. The Aerospace Exploration Agency (J, A, X, A), Japan's space research agency, said in a statement that the most primitive feature has been identified in Rouge among any natural specimens found so far, including meteorites. It is thought that part of the asteroid material was formed about 5 million years after the origin of the solar system and did not warm above 100 degrees Celsius.

Another research article was published in the American journal Science. That said, the material contains a chemical compound that is more in tune with the sun's luminosity than other natural specimens.

Kensai Kobayashi, an astrobiologies and emeritus professor at Yokohama National University in Japan, welcomed the discovery as surprising.

Scientists have questions about how organic matter, including amino acids, came from or where it came from, said Kensei Kobayashi. The fact that amino acids have been identified in asteroid samples will give you a chance to think that it came to Earth from space.
