Catching the Amazing Lights极光之旅
Around the North and South Poles（北极和南极） of our planet（星球）， sometimes we can see beautiful lights in the sky. We call them auroras（极光）.
Scientists say that the sun brings auroras. There are many small particles（粒子） going from the sun to our planet.When they go through our atmosphere（大气层）， they light it up（把它点亮）. This is what we call an aurora.
Do you know where we can see the most beautiful auroras？ Here are some good places.
Sometimes we also
call auroras around the
