Where can you see auroras(极光)? Iceland? The North Pole? Actually, early this December, sky lovers in cities as south as Beijing could see them too. They enjoyed the coloured lights in the night sky.
Auroras come about because of the special activities of the sun. The sun sends out very small particles(粒子) all the time. But sometimes, it becomes more active and lets out more. The particles travel in space like a wind. When they come near the earth, they go around it. This is because the magnetic field(磁场) of the earth "protects" us from the "wind".
At the North and South Poles, however, some particles may get in and meet with the earth's air. Then, the particles get "excited" and have a "dance" with the air. So, we can see the moving auroras in the sky. When the "wind" is strong enough, the auroras can cover larger areas. While we are wowed by the beautiful lights, we often ask, "Do auroras hurt us?" The answer is no. Auroras don't hurt people's health. But for astronauts(航天员) in space, they need to use special ways to protect themselves from them, said Xinhua. For example, they won't go on spacewalks when there are "sun storms". Also, the particle storms may stop some satellites(卫星) from working, so they may bring trouble to the GPS on our smartphones.
