MIT finds traces of a lost world deep within planet Earth
MIT scientists have uncovered chemical traces of the original "proto Earth” remnants from before the cataclysmic impact that created our modern planet

Researchers from MIT and collaborating institutions have uncovered exceptionally rare traces of "proto Earth," the ancient precursor to our planet that existed about 4.5 billion years ago. This primitive world took shape before a massive collision forever changed its chemistry and gave rise to the Earth we inhabit today. The discovery, described on October 14 in Nature Geosciences, could help scientists reconstruct the earliest ingredients that shaped not only Earth but also the rest of the solar system.
