A single pound of ancient stone, pulled from the Sahara and catalogued without ceremony, may carry within its crystals the memory of a world that ceased to exist billions of years ago. Researchers examining the rare angrite meteorite NWA 12774 found pressure signatures so intense they could only have formed inside a planetary body comparable in scale to the Moon — a world that collided, fragmented, and vanished long before Earth finished assembling itself. The early solar system was not only a nursery of planets but a graveyard of them, and this small rock may be one of the few legible epitaph
