From October 3 to 13, 2025, the Fête de la Science is the place to be for young and old alike when it comes to science. Numerous venues in and around Paris are offering workshops, festivals, exhibitions and tours open to all, and 100% free of charge.
Over ten days of programming, researchers are committed to raising public awareness of a wide range of scientific subjects, including astronomy, biology and archaeology, through exciting fun activities. It's a great way to expand your knowledge and, who knows, discover a new passion!
Why not discover our sky in greater depth in the Yvelines? TheObservatoire de Meudon was created in the 19th century as a place dedicated to astrophysics, a science that had been little studied until then. Attached to the Paris Observatory in 1927, it is famous for its terraces, from which you can enjoy a panoramic view of Paris, and is also a green space located in the Domaine national de Meudon.
Please note: workshops must be booked in advance!
