Core Insights - The Chinese Academy of Sciences announced significant research findings from the Chang'e 6 lunar samples, published in the journal Nature, revealing the evolutionary history of the moon's far side [1][2] Group 1: Research Findings - Four key research achievements were made using the Chang'e 6 samples, including the discovery of volcanic activity on the moon's far side approximately 4.2 billion and 2.8 billion years ago, indicating such activity lasted for at least 1.4 billion years [2] - The ancient magnetic field information was obtained for the first time, suggesting that the moon's magnetic field strength may have rebounded around 2.8 billion years ago, indicating fluctuations rather than a monotonic decline [2] - The water content in the moon's mantle on the far side was found to be significantly lower than that on the near side, indicating a "bipolarity" in the moon's internal water distribution [2] - The basalt on the moon's far side was discovered to originate from a highly depleted source region, suggesting that large impact events may have significantly influenced the evolution of the moon's deep layers [2] Group 2: Impact of Research - The South Pole-Aitken Basin, a major lunar structure with a diameter of approximately 2,500 kilometers, was highlighted as a key area of study, with the impact energy from its formation being equivalent to a trillion times that of an atomic bomb [2] - The research published in Nature systematically reveals the effects of the South Pole-Aitken impact, marking a significant advancement in understanding lunar evolution [2] - Other breakthroughs from the Chang'e 6 samples include the first study revealing the physical, mineral, and mantle evolution characteristics of the samples, and the precise dating of the South Pole-Aitken Basin's formation to 4.25 billion years ago, providing a more accurate "cosmic clock" for understanding early solar system impacts [2]
