Apollo rocks reveal the Moon had brief bursts of super-strong magnetism

Scientists at the University of Oxford have finally settled a decades-long mystery about the Moons magnetic field - and it turns out both sides were right. By reanalyzing Apollo mission rocks, they discovered that the Moon did occasionally generate an incredibly powerful magnetic field, even stronger than Earths - but only for fleeting bursts lasting thousands of years or less. Most of the time, the Moons magnetic field was weak.
