China’s Chang’e-6 mission brought back moon dust that’s hiding a wild secret: scientists found traces of a super-rare, water-rich meteorite never seen on the Moon before! These fragile CI chondrites usually don’t survive impacts, so finding them means ancient water-filled asteroids bombarded the Moon (and probably Earth) way more than we thought. Basically, this tiny dust is rewriting what we know about how water—and maybe life—got here. Space history in a handful of grains! #Science #MoonDiscovery #SpaceScience
