Chang’e-6 lunar soil contains a surprising magnetic time capsule

Scientists studying Chang’e-6 lunar soil have discovered a previously unknown magnetic mineral in natural Moon samples: a form of metallic iron called γ-Fe. Found inside tiny impact-glass particles, the nanoscale iron can preserve a stable magnetic signal, potentially acting like
