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

What happened

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 a microscopic fossil of the Moon’s long-lost magnetic field.

Researchers analyzing metallic iron inside impact glass from Chang'e-6 lunar soil have now identified face-centered cubic γ-Fe for the first time in natural lunar samples. The findings were published in the Proceedings of the National Academy of Sciences (PNAS) on September 16.
