Astronomy can be defined as the science of the observation of the stars. It makes it possible to establish the origin, the evolution, the physical and chemical properties of the stars as well as the functioning of the celestial mechanism. Although it is a science more or less complex, astronomy is attracting a lot of interest from an increasingly wide audience and from all walks of the planet. In France in particular, each year is organized La Nuit des Etoiles with the aim of bringing together all amateur astronomers.
