11 February 2026 Ten years since the first reported observation of gravitational waves In 2016, the first direct observation of gravitational waves was reported. The measurements by the LIGO detectors gave astronomers a new way to observe the Universe.

On 14 September 2015, the two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors in the United States recorded a brief signal that lasted for about 0.2 seconds. This signal was caused by a gravitational wave from the final orbits and subsequent merger of two black holes. The wave had propagated through the Universe for more than 1.3 billion years before passing through Earth. Although this gravitational wave carried the energy equivalent of three solar masses away from its source, its effect on Earth was minuscule: the wave caused a periodic length variation in the LIGO detectors of around 10−18 metres.
