Open days 2026: celebrating 200 years of Observatory
This autumn, you will get the unique opportunity to step onto the grounds of the Space Pole in Uccle. A weekend of fun and games for the youngest, scientific discovery for the whole family and direct interaction with the scientists themselves. This year the Observatory is celebrating its bi-centennial anniversary.
Whether you come to see the telescopes or to learn about the weather, the climate, the aurora or the planets of the solar system, we have it all lined up for you. See you then!
