On September 14th 2015, ten years ago, a signal arrived on Earth that was generated by a pair of black holes. After spiralling around each other at impressive speeds, they had merged, releasing an enormous amount of energy. To reach us, the signal had travelled some...

LIGO, Virgo and KAGRA celebrate the anniversary of the first gravitational waves detection and announce verification of Stephen Hawking's Black Hole Area Theorem. On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes...

We are deeply saddened to hear about the passing of Rainer Weiss, one of the fathers of gravitational wave research, founder of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Nobel Prize laureate in physics for the detection of gravitational waves....

August 26th 2025 marks an important date for the international LIGO, Virgo, and KAGRA (LVK) gravitational-wave network. The collaborations are releasing the interferometric strain data from the first part of the fourth observing run (O4a) that took place from May...
