18 researchers from the Chinese Academy of Sciences, assess #paleointensity β a measure of historical #magneticfield. #Basalt samples thought to be 2.8B years old. Analysis suggests Moon's magnetic field has increased in strength. Moon once possessed a strong "dynamo" β the term for forces that create celestial bodies' magnetic fields β but it weakened around 3.1B years ago and shut down around 1B years ago.
