Aurora Borealis

An aurora is a natural light display in the sky (from the Latin word Aurora "sunrise" or the Roman goddess of dawn),

Auroras are natural different colored light displays, which are usually observed in the night sky, particularly in the polar zone. In northern latitudes, it is known as the aurora borealis, named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas. It often appears as a greenish glow (or sometimes a faint red), as if the sun were rising from an unusual direction. The aurora borealis is also called the ‘northern lights’, as it is only visible in the North sky from the Northern Hemisphere. The aurora borealis most often occurs from September to October and from March to April.
