Arthur Eddington presents the results of the May 1919 eclipse expeditions to Principe and Sobral at a joint session of the Royal Society and the Royal Astronomical Society at Burlington House. The measured deflection of starlight matches Einstein's prediction, and the meeting accepts it.

At a press conference at the National Press Club in Washington, the LIGO and Virgo collaborations announce GW150914, a signal from the merger of two black holes recorded by both LIGO detectors on 14 September 2015 - the first direct observation of gravitational waves.

The gravitational-wave detectors start a six-month intermediate observing run before the fifth observing run. Both LIGO detectors take part, Virgo joins despite possible maintenance interruptions, and KAGRA joins as it becomes available.

The first stage of Euclid Data Release 1 puts out all raw data and calibrated images, catalogues and spectra over about 1,900 square degrees of sky. The higher-level products for galaxy clustering and weak lensing follow in mid-2027.

La ESA publica la cuarta entrega de datos de Gaia, la primera entrega principal de la misión, que cubre los primeros 5,5 años de observaciones. Incluye series temporales astrométricas, una lista de exoplanetas y el software para trabajar con ellos.

ESO's 39-metre Extremely Large Telescope takes its first test observations from Cerro Armazones in March 2029, with scientific first light following in December 2030.

A 340-metre asteroid passes about 32,000 km from Earth, closer than geostationary satellites and visible to the naked eye from Europe and Africa.

The SKA's mid-frequency array in South Africa's Karoo reaches AA2 in 2029, two years after its Australian counterpart, opening science verification observations.
