An
aurora (plural:
auroras or
aurorae) is a natural light display in the
sky, particularly in the
polar regions, caused by the collision of charged particles directed by the Earth's
magnetic field. An aurora is usually observed at
night and typically occurs in the
ionosphere. It is also referred to as a
polar aurora or, collectively, as
polar lights. These phenomena are commonly visible between 60 and 72 degrees north and south latitudes, which place them in a ring just within the Arctic and Antarctic polar circles.
[citation needed] Auroras do occur deeper inside the polar regions, but these are infrequent and often invisible to the naked eye.
In northern
latitudes, the effect is known as the
aurora borealis (or the
northern lights), named after the
Roman goddess of dawn,
Aurora, and the
Greek name for the north wind,
Boreas, by
Pierre Gassendi in 1621.
[1] The chance of visibility of the aurora borealis increases with proximity to the
North Magnetic Pole.
[citation needed] Auroras seen near the magnetic pole may be high overhead, but from farther away, they illuminate the northern horizon as a greenish glow or sometimes a faint red, as if the Sun were rising from an unusual direction. The aurora borealis most often occurs near the
equinoxes. The northern lights have had a number of names throughout history. The
Cree call this phenomenon the "
Dance of the Spirits". In Europe, in the
Middle Ages, the auroras were commonly believed a sign from God (see Wilfried Schröder, Das Phänomen des Polarlichts, Darmstadt 1984).
Its southern counterpart, the
aurora australis (or the
southern 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".
Auroras can be spotted throughout the world and on
other planets. They are most visible closer to the poles due to the longer periods of darkness and the magnetic field.
Modern style guides recommend that the names of meteorological phenomena, such as
aurora borealis, be uncapitalized.

P.S.
I think I posted an entry a few months back about the Aurora Borealis but I couldn't find it. :) What I know is I've been fascinated by it since my childhood years. I hope to see one soon!
