Moon's Soil Reveals 100-Million-Year Record of Distant Supernovas

For a hundred million years, the Moon has been quietly collecting the ash of dying stars — a cosmic archive far older than anything Earth's oceans can preserve. Researchers at the University of Hawaiʻi at Mānoa have built a mathematical key to read this scrambled record, decoding how meteorite impacts bury and resurface supernova debris across deep time. In doing so, they have transformed the lunar surface from a barren landscape into a library of the Solar System's galactic wanderings — one that future missions may finally open.
