美国宇航局:月球曾经有磁场保护地球免受太阳辐射
According to a new study by NASA, earth’s natural satellite – the moon, once shared a magnetic field with the earth that protected it from solar radiation and played a key role in the evolution of life. “The Moon seems to have presented a substantial protective barrier against the solar wind for the Earth, which was critical to Earth’s ability to maintain its atmosphere during this time,” said Jim Green, NASA’s chief scientist.
根据美国国家航空航天局的一项新研究，地球的卫星——月球，曾经和地球共享一个磁场，保护它不受太阳辐射，并在生命的进化中发挥了关键作用。美国宇航局首席科学家吉姆·格林(Jim Green)说:“月球似乎为地球提供了一个抵御太阳风的实质性屏障，这对地球在此期间维持大气层的能力至关重要。”
