New lunar research reveals the moon had a lasting magnetic field 2 billion years ago, challenging past theories.

New research on samples from China's Chang'e-5 mission shows the moon had a weak magnetic field around 2 billion years ago. This suggests the moon's dynamo lasted longer than previously thought, offering insights into its internal structure, thermal history, and surface conditions, including potential for water presence. The magnetic field, about 2 to 4 microteslas, indicates a protective shield that could help in studying lunar space weathering.
