11th and last Open Day at GEO600

Visit the gravitational-wave detector near Sarstedt on 4 July 2026
Fields stretch to the horizon, with several buildings, two long tunnels at ground level, and a parking lot in the foreground, surrounded by green spaces.

The GEO600 project will end on 31 December 2026

More than three decades of cutting-edge research at the German-British detector have shaped the international field of gravitational-wave astronomy.

Technology development for gravitational-wave astronomy

GEO600 is a key technology development center of the international gravitational-wave research community. Technologies developed and tested in the GEO project are now used in all large gravitational-wave detectors in the world.
