About Paris-PSL Observatory
Founded in 1667, the Observatoire de Paris has been a center of innovation and discovery in astronomy for over 350 years. With 750 researchers and teacher-researchers, engineers, technicians and administrative staff, the establishment conducts research on its 3 campuses in astrophysics, physics, engineering and the metrology of time and space. Its work combines theory, numerics, experimentation, ground-based and space-based observations, and instrumental development.
Paris Observatory produces French legal time, ephemerides of the Sun, Moon and solar system bodies, and operates state-of-the-art radio telescopes at Nançay. It offers academic training (Masters, PhD), training for the general public and teachers, and class sponsorship. It is a founding member of the Université Paris Sciences et Lettres.
