极光的形成最早记录北极光的是挪威编年史《国王的镜子》,成书大约在1230年。直到17世纪后期,英国天文学家埃德蒙·哈雷才第一次将极光与地球磁场联系起来。法国科学家让·雅克·德麦兰是第一个提出极光和太阳有关的人。人们发现,当太阳风到达地球,它们被看不见的盾牌——地球磁场所偏转。地磁层是地球周围一个看不见、摸不着的巨大磁化区域,是太阳高能带电粒子的天然屏障,正是有了这道屏障我们才能安稳地 Aurora formation The earliest record of the Northern Lights is the Norwegian Chronicle “The Mirror of the King”, book about 1230 years. It was not until the late 17th century that British astronomer Edmund Harley first linked Aurora to the Earth's magnetic field. Jean Jacques de Meran, a French scientist, was the first to suggest auroras and the sun. People find that when the solar wind reaches the Earth, they are deflected by invisible shields - Earth's magnetic field. The geomagnetic layer is an invisible and invisible giant magnetized area around the earth and is a natural barrier to the solar high-energy charged particles. It is with this barrier that we can safely
