New Insights from an Ancient Asteroid

Quote

In June 2018, Japan's Hayabusa2 spacecraft retrieved samples from asteroid Ryugu and successfully returned them to Earth. Researchers at Tohoku University have analysed the samples and identified what they believe may be the oldest solids from the solar system that have thus far become available for study. They reported their findings in the journal Nature Communications on February 16, 2023. The article was also selected to feature in the Editors' Highlights.

Very interesting story, thanks for sharing below is a copy of the Peer Reviewed Journal from Nature that was Published February 16, 2023!

Chondrule-like objects and Ca-Al-rich inclusions in Ryugu may potentially be the oldest Solar System materials: https://www.nature.com/articles/s41467-023-36268-8

Asteroid Samples Suggest , Origin of Life on Earth , May Have Come Via Impact. Scientists have now confirmed that samples taken from the asteroid Ryugu contain organic molecules. . Gizmodo reports that the revelation adds credence to the theory that the origin of life on Earth could have been delivered via meteorite and asteroid impacts. Ryugu is a rocky remnant leftover from the formation of our solar system over 4 billion years ago. . The primitive carbonaceous asteroid was visited by Japan's Hayabusa2 mission, which gathered samples from the surface back in 2019.

Among other compounds, scientists found 15 different amino acids, amines and aromatic hydrocarbons in the samples. . The presence of prebiotic molecules on the asteroid surface despite its harsh environment caused by solar heating and ultraviolet irradiation, as well as cosmic-ray irradiation under high-vacuum conditions, suggests that the uppermost surface grains of Ryugu have the potential to protect organic molecules, Hiroshi Naraoka.

The presence of prebiotic molecules on the asteroid surface despite its harsh environment caused by solar heating and ultraviolet irradiation, as well as cosmic-ray irradiation under high-vacuum conditions, suggests that the uppermost surface grains of Ryugu have the potential to protect organic molecules, Hiroshi Naraoka.  These molecules can be transported throughout the solar system, potentially dispersing as interplanetary dust particles after being ejected from the uppermost layer of the asteroid by impacts or other causes, Hiroshi Naraoka, Planetary scientist at Kyushu University in Japan and the paper’s lead author, via 'Gizmodo'. The team's findings were published in 'Science.'. Gizmodo reports that NASA's OSIRIS-REx mission is currently returning from an asteroid known as Bennu, where it completed similar sampling operations.

Interesting. Would explain the fruitless Miller-Urey experiments.
