You must have seen a rainbow in the daytime but have you seen a rainbow at night. Probably not, because of this a Polar light.
Polar light is a light that exists only in the poles. These polar lights are better known as AURORA.
Aurora is the reddish and green light that form in the sky due to disturbance in the thermosphere (one of the layers of the atmosphere) due to solar winds.
The light on the North Pole is called northern light or the Aurora Borealis, it means wind from the goddess of dawn. The light on the South Pole is called Aurora Australis.
