Researchers propose new explanation for Moon’s half-century magnetic mystery
Rocks returned to Earth during NASA’s Apollo program from 1968 to 1972 have provided volumes of information about the Moon’s history, but they’ve also been the source of an enduring mystery. Analysis of the rocks revealed that some seemed to have formed in the presence of a strong magnetic field—one that rivaled Earth’s in strength. But it wasn’t clear how a Moon-sized body could have generated a magnetic field that strong.
