Detecting and measuring gravitational waves requires the use of extremely sensitive instruments. Laser interferometry was pioneered in the 1970s by American physicist Rainer Weiss. This technique uses ...

The LIGO-Virgo-KAGRA (LVK) collaboration recently began a new observing run that promises to take gravitational-wave astronomy to the next level. According to scientists from across the ...

In the joint research project “3G-GWD”, scientists at Laser Center Hannover (LZH) is working on the development of new laser sources for future, more sensitive gravitational wave detectors of the next ...

Due to come online later this year and packed with state-of-the-art optics, Advanced LIGO is aiming for a direct detection of gravitational waves that will open a new window on the universe, say Iain ...

Last month, work began on the world’s first space-based gravitational wave detector. The European Space Agency and partner aerospace companies are developing orbiting, detector spacecraft to observe ...

In September 2015, a vibration lasting just one-fifth of a second changed the history of physics. It was the first direct detection of gravitational waves — perturbations in the geometry of space-time ...
