A fragment of the early solar system, pulled from the Sahara and small enough to hold in one hand, has led scientists to conclude that a world nearly the size of the Moon once formed, evolved along its own chemical path, and was destroyed before Earth had finished taking shape. The meteorite known as Northwest Africa 12774 belongs to a rare class of ancient rocks whose mineral crystals bear the unmistakable signature of pressures that only a large planetary body could generate. In recovering this lost world from a single stone, researchers remind us that the solar system we inhabit is only the
