嫦娥六号样品发现罕见“天外信使”

Core Insights - The research from China's Chang'e 6 lunar samples provides crucial clues about the origin of water on the Moon and the ability of outer solar system materials to travel to the inner solar system [1][2] Group 1: Research Findings - The team led by Academician Xu Yigang and Researcher Lin Mang from the Guangzhou Institute of Geochemistry successfully identified impact remnants of CI carbonaceous chondrites in the Chang'e 6 lunar samples [2] - The identified fragments are products formed from the melting and rapid cooling of the parent body of these chondrites after impacting the lunar surface [2] - A new method for effectively identifying extraterrestrial samples containing meteoritic materials was established [2] Group 2: Implications of Findings - CI chondrites, which are rich in water and organic materials, are primarily found in the outer solar system, and their presence on the Moon is significantly higher than on Earth [2] - This suggests that the contribution of carbonaceous chondrites to the Earth-Moon system may have been severely underestimated [2] - The findings confirm that materials from the outer solar system can migrate inward, providing new directions for future research on lunar water resources and their evolution [2]
