Solved: New analysis of Apollo Moon samples finally settles debate about lunar magnetic field

University of Oxford
Peer-Reviewed Publication

Researchers from the Department of Earth Sciences, University of Oxford, have resolved a long-standing debate about the strength of the Moon’s magnetic field. For decades, scientists have argued whether the Moon had a strong or weak magnetic field during its early history (3.5 - 4 billion years ago). Now a new analysis – published today (26 February) in Nature Geoscience – shows that both sides of the debate are effectively correct.
