Aurora is a colorful luminous phenomenon that appears above the planet's high magnetic latitudes. The aurora is due to the solar charged particle flow (solar wind) into the Earth's magnetic field, in the north and south poles of the Earth near the region of the sky, the brilliant beauty of the night. In the South Pole is called the South Pole Light, in the North Pole is called the Northern Lights. The Earth's aurora is produced by a stream of high-energy charged particles (solar wind) from the Earth's magnetosphere or sun that excites (or ionized) molecules or atoms in the upper atmosphere.
Auroras often appear over latitudes near the geomagnetic poles and are generally banded, curved, curtain-like, radiant, and these shapes are sometimes stable and sometimes continuous. The aurora produces three conditions: the atmosphere, the magnetic field, and the high-energy charged particles. All three are indispensable.

Auroras do not only appear on Earth, but also on other magnetic planets in the solar system.
