Observatory of Geneva

The Observatory of Geneva is an astrophysics research facility in Versoix with multiple locations dedicated to studying stars, planets, and distant objects in space. The main site at Sauverny contains observation equipment and laboratories, while a separate facility handles data analysis and processing.

The site was established in 1772 and remains one of Switzerland's oldest scientific institutions. In 1995, researchers made a groundbreaking discovery by confirming the first planet orbiting a sun-like star beyond our solar system.

The facility serves as a major research hub that attracts scientists from across Europe and beyond to study the cosmos. Visitors experience how fundamental questions about space are explored through everyday scientific work and collaboration.

Visitors can explore the Sauverny site and take tours to learn about the research work and observation equipment used by scientists. It is helpful to check opening times and registration requirements in advance so you can plan your visit accordingly.

The facility operates telescopes at multiple locations outside Switzerland, including major equipment in Chile and observation stations in the Canary Islands. This geographic spread allows researchers to observe celestial objects from different positions and gather more comprehensive data across the night sky.
