For a long time considered as supernatural phenomena, the polar auroras have fascinated mankind, and still do today. Over the centuries, scientists have tried to prove that these phenomena had nothing divine but everything physical. It was not until the 18th century that Birkeland realized a device to recreate auroras. Today, scientific institutions such as the National Aeronautics and Space Administration and the European Space Agency are constantly observing and analysing solar activity, which is responsible for meteorological changes, but also for the appearance of polar auroras.
This thesis is composed of seven main chapters in which it is explained how the northern lights are formed, from their origins to their appearance in the sky. There are also the myths and legends around which the aurora has been talked about, as well as the way to detect and predict them.
It is possible to note that the aurora borealis involves various physical and chemical phenomena, of a complexity both at the atomic level and at the macroscopic scale. The detection of the aurora borealis includes several criteria such as the Kp index, the presence of clouds and light pollution. As for their prediction, despite today's new technologies, accurately predicting the arrival of this phenomenon remains a very complicated task that requires time.
