Chang’e-6 soil reveals metallic iron in lunar samples; it may preserve clues to Moon’s lost magnetic field

Recent analysis of lunar soil samples returned by China's Chang’e-6 mission revealed a unique form of iron. This iron, γ-Fe, exhibits exceptional magnetic properties, which could provide insights into the Moon's ancient magnetic field. Researchers suggest that extreme impacts on the lunar surface caused the formation and preservation of this unusual iron. The findings could enhance our understanding of the Moon's geological history and its evolution over time.
