Aurora Borealis

Aurora Borealis is a natural light display that occurs in the polar regions of a planet. They are also known as Northern Lights and Polar Lights.

History
They are caused by solar winds disturbing the magnetosphere.

On the planet Earth, auroras would light up the night sky in the northern regions of Canada, like Baffin Island. One night, when Sabretooth captured and threatened to kill a Inuit village, auroras occurred in the sky while he fought with Wolverine.
