The seeds of an Earth-like life form surprisingly exist directly on the surface layer of the Dragon Palace – the Ryugu asteroid that Japan successfully sampled.
A new analysis of Ryugu meteorite sample – aka “Dragon Palace” in Japanese mythology – shows that it contains many “prebiotic organic matter”includes several amino acids that living organisms on Earth use to make proteins needed to regulate biochemical reactions, forming structures such as hair and muscles.
According to the sheet Spacethese findings added credibility to the hypothesis that the basic ingredients to start the chain of development of life on Earth came from asteroids and comets.

“The presence of prebiotic molecules on the surface of the asteroid despite the harsh environment caused by solar heating and ultraviolet radiation, as well as cosmic radiation under high vacuum conditions, suggests that particles from Ryugu’s upper surface have the ability to protect organic molecules.” – said lead author Hiroshi Naraoka from Kyushu University.
Existing on the surface rather than just organic matter mixed with an asteroid’s material raises the importance of “Dragon Palace” has long been known to be rich “seed of life” Hey.
Dr. Naraoka further explains: “These molecules can be transported throughout the solar system, potentially dispersing as interplanetary dust particles after being ejected from the upper layer of the asteroid by impact or other causes.
This increases the likelihood that the seeds of life will reach planets like Earth: it is not necessary for the entire asteroid to crash into the early Earth, just for the dust particles from it to spread everywhere by the chain of collisions. incessant contact was enough.
On Ryugu there are not only regular organic elements but also shapes “prebiotic molecule” forms when there is liquid water, partly “high society” for the life-forming process.
“So far, the amino acids found in Ryugu mostly match those seen in carbon-rich meteorites that were exposed to the greatest amount of water in space.” – said co-author Jason Dworkin from NASA’s Goddard Space Flight Center.
Scientists around the world continue to analyze the Ryugu samples – which have been divided into many different groups in many different countries – to look for elements closer to DNA and RNA, in order to further strengthen plus the theory. We are from the universe.
