With more than 30 years of groundbreaking research and technological innovation, GEO600 is one of the most influential detectors in the history of the field. It is a facility that has fundamentally shaped how gravitational-wave detectors are conceived, constructed, and operated.

In the March 2026 issue of LIGO Magazine (pages 33 and following), Harald Lück and Michael Weinert (on behalf of the entire team) discuss how the German-British gravitational-wave detector is more than just technology. It is a place of collaboration and exchange that brings scientists from around the world together. It is also a training ground for generations of young researchers and an environment in which boundaries are continuously pushed through the creative use of science and technology.

The article also presents the first results from the GEO600 very high frequency project: a first attempt at presenting calibrated GEO600 measurement data at frequencies of up to 2 MHz.
