Scientists studying lunar samples brought back by China's Chang'e-6 mission have identified rare meteorite relics that could reshape our understanding of material transfer in the Solar System. Using advanced techniques to examine mineral composition and oxygen isotopes, researchers analyzed lunar soil and confirmed that the fragments came from CI-like chondrites – a type of meteorite rich in water and organic materials that typically originates in the outer Solar System. The study suggests that the Earth-Moon system may have experienced more collisions with carbonaceous chondrites than previously estimated.
