Scientists find lunar 'magnetic fossil' in Chang'e-6 samples

Researchers have found a lunar 'magnetic fossil' — traces of ancient magnetism — in samples returned by China's Chang'e-6 mission. Studying the magnetic minerals could reveal how the Moon's magnetic field evolved, as it no longer has a global field today.

• Samples were returned by China's Chang'e-6 mission
• The rocks preserve records of ancient magnetism
• The Moon currently has no global magnetic field
• Mineral analysis may clarify the field's evolution
