What are the northern lights?

The northern lights are a common term referring to the aurora borealis. The aurora borealis is a natural phenomenon seen in the northern hemisphere near the arctic circle. Auroras are caused by disturbances in the magnetosphere caused by solar winds which result in emissions of light of varying colours and complexities.
