Short Definition: An aurora (plural: auroras or aurorae) is a
sporadic atmospheric phenomenon occurring usually in the night at high latitudes.
Detailed Definition: An aurora is a phenomenon caused by the Sun
(star). A bust of electrified gas (solar wind) from the star approaches planets.
Small particles travel down the magnetic field lines towards both poles.
Particles from the star interact with gas particles in the atmosphere, causing the creation
of the light in the sky. Depending on the atmosphere composition, the colour of the
aurora might be different. Oxygen glows green and red, nitrogen blue and
purple. Auroras can appear on every celestial object that has an atmosphere and
magnetic field. On Earth, the aurora near the North Pole is called an aurora
borealis (northern light) and one near the South Pole is called an aurora
australis (southern light).
