Moon's Regolith Unlocks Supernova History Through Impact Gardening Model

Across millions of years, the deaths of distant stars have been quietly writing their histories into the dust of the Moon — a record that Earth, with its restless geology, cannot keep. Researchers at the University of Hawaii have built a mathematical model to read that record, decoding how meteoroid impacts, radioactive decay, and space weathering together preserve the isotopic fingerprints of ancient supernovas in the lunar regolith. Their framework, validated against Apollo-era samples, transforms the Moon from a scarred and silent body into something closer to a library of cosmic time — one
