It is a phenomenon in the form of brightness or luminescence that occurs in the night sky, generally in polar areas, although it can appear in other areas of the world for brief periods.
The best times to observe it are between September and March in the northern hemisphere (aurora borealis), and between March and September in the southern hemisphere (aurora australis).
The northern lights were observed and probably greatly impressed the ancients. In both the West and China, auroras were seen as snakes or dragons in the sky.
In 1621, the French astronomer Pierre Gassendi described this phenomenon observed in the south of France and gave it the name polar aurora.
