This phenomenon in the sky is known as Aurora, which is a natural light display in the sky. Aurora can be seen in the high latitude regions, like the Arctic and the Antarctic.
A region displaying an aurora at any given time is known as the auroral oval, a band which is displaced towards the nightside of the Earth.
