Aurora (astronomy)

Auroras, also known as northern and southern (polar) lights or aurorae, are natural light displays in the sky, particularly in the polar regions, and usually observed at night. They typically occur in the ionosphere. They are also referred to as polar auroras. This is a misnomer however, because they are commonly visible between 65 to 72 degrees north and south latitudes, which place them a ring just within the Arctic and Antarctic circles.
