The Observatory at Meudon

Founded in 1876 through the initiative of Jules Janssen, this observatory is entirely devoted to astrophysics, a completely new discipline in his time. It gradually acquired impressive and innovative instruments. Although it joined forces with the Paris Observatory in 1926, it has nevertheless kept its scientific specificity. Nocturnal observations have ceased, but the Sun is observed daily whenever possible, and many astrophysicists continue to work at the Observatory.
