They discovered that the Moon’s magnetic field may have experienced a rebound around 2.8 billion years ago, suggesting that the Moon’s generator may have been reinforced after an early sharp decline.
“The reason for this rebound could be a change in the primary energy source of the generator or a restrengthening of the initial driving mechanism,” Cai said.
“The data fill in a billion-year gap in the evolution of the lunar paleomagnetic record and provide the first paleomagnetic measurements from the lunar far side,” a reviewer for the journal Nature said. “The authors are to be congratulated on a historic study that provides a major advance in our understanding of lunar magnetism.”
The evolution history of the Moon’s magnetic field is markedly different from that of the Earth’s, the research team said.
