The Aurora Borealis shines above Bear Lake

Auroras (north/south polar lights; or aurorae, sing.: aurora) are natural light displays in the sky, usually observed at night, particularly in the polar zone. They typically occur in the ionosphere. They are also referred to as "polar auroras". In northern latitudes, the effect is known as the aurora borealis, and it was named after the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas by Pierre Gassendi in 1621[1]. The aurora borealis is also called the northern polar lights, as it is only visible in the sky from the Northern Hemisphere, the chance of visibility increasing with proximity to the north magnetic pole, which is currently in the arctic islands of northern Canada. Aurorae seen near the magnetic pole may be high overhead, but from further away, they illuminate the northern horizon as a greenish glow or sometimes a faint red, as if the sun was rising from an unusual direction. The aurora borealis most often occurs from September to October and from March to April. The Cree call this phenomenon the Dance of the Spirits.



Its southern counterpart, the aurora australis/southern polar lights, has similar properties, but is only visible from high southern latitudes in Antarctica, South America or Australasia. Australis is the Latin word for "of the South". The northern lights have had a number of names through history.



Benjamin Franklin first brought attention to the "mystery of the Northern Lights." He theorized the shifting lights to a concentration of electrical charges in the polar regions intensified by the snow and other moisture.[2]
