After a prolonged absence from the gravitational-wave-detection scene, the massive LIGO project is back up and running. The Laser Interferometer Gravitational-Wave Observatory (LIGO) works in ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

After a three-year hiatus made longer by pandemic troubles, the search for gravitational waves — ripples in space-time that are the hallmarks of colliding black holes and other cosmic cataclysms — has ...

Putting the squeeze on light improves gravitational wave observatories. An upgrade to one such observatory, LIGO, that comes from exploiting a quantum rule known as the Heisenberg uncertainty ...

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the LIGO observatories. The powerful merger produced a ...

It has been three years since the Laser Interferometer Gravitational-Wave Observatory (LIGO) shut down, starting a long hiatus from searching the universe for gravitational waves. Now, though, the ...

Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

Ten years after LIGO’s historical detection of gravitational waves, the project is cracking black hole mysteries at an astounding pace. Reading time 4 minutes LIGO’s discovery of gravitational ...

A lot has happened in gravitational-wave astronomy over the past decade. Sept. 14, 2015, was one of the most important days in science history. It marked the first-ever detection of gravitational ...
