一项新研究显示,地球磁场形成于34.5亿年前。这表明,地球磁场形成的时间比先前人们认为的提前了约25亿年。地球磁场形成的时间与地球上最初生命的形成时间相符,地球磁场的形成有效地避免了地球上最初的生命形态遭受太阳磁辐射的破坏。这项研究成果发表在《科学》(Science)杂志上。
A new study shows that the earth’s magnetic field was formed 3.45 billion years ago. This shows that the Earth’s magnetic field was formed about 2.5 billion years earlier than previously thought. The formation of the Earth’s magnetic field coincides with the formation of the first life on the Earth. The formation of the Earth’s magnetic field effectively avoids the destruction of the original life form on Earth by solar magnetic radiation. The research is published in Science.
