Northern Lights

An aurora (plural: aurora or aurora) are natural light displays in the sky, particularly in the polar regions, which are caused by charged particle collisions are directed by the earth's magnetic field. An aurora is usually observed at night and usually occur in the ionosphere. This is also referred to as the polar aurora or, collectively, as a light pole.
This phenomenon is usually seen between 60 and 72 degrees latitude north and south, which puts them in the ring only in the Arctic and Antarctic circles the poles. Aurora does happen more in the polar regions. but this is rare and often invisible to the naked eye.


In northern latitudes, this effect is known as the aurora borealis (or northern lights), named after the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas, by Pierre Gassendi in 1621. opportunities to increase the visibility of the aurora borealis by its proximity to the Magnetic North Pole. [citation needed] aurora seen near the magnetic pole may be high overhead, but from afar, they illuminate the northern horizon as a light greenish or sometimes a faint red, as if the sun were rising from an unusual direction. That aurora borealis most often occurs near the equinoxes. Northern Lights has several names throughout history. The Cree call this phenomenon "Dance of the Spirit. " In Europe, the Middle Ages, the aurora is generally believed to be a sign from God (see Wilfried Schröder, Das Phänomen des Polarlichts, Darmstadt 1984).

Its southern counterpart, aurora australis (or southern lights), have the same nature, but only visible from high southern latitudes in Antarctica, South America, or Australasia. Australis is the Latin word for "south".

Aurora can be seen all over the world and on other planets. They are the most visible closer to the poles due to long periods of darkness and magnetic fields.

Modern style guides recommend that the names of meteorological phenomena, such as the aurora borealis, will uncapitalized.
