Moon's Origins Remain Unsolved Despite Apollo Samples, New Research Shows

Four and a half billion years ago, a violent collision may have forged the Moon from the wreckage of a young Earth — yet despite half a century of study and the rare gift of actual lunar rocks, science cannot fully account for what happened. The Moon's chemical kinship with Earth defies the very models built to explain its birth, leaving planetary scientists caught between elegant theory and stubborn evidence. This is not merely a question about a distant satellite; it is an unresolved chapter in the story of how our own world came to be.
