On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to ...

Researchers have demonstrated a new, unsupervised machine learning approach to find new patterns in the auxiliary channel data of the Laser Interferometer Gravitational-Wave Observatory. Finding ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The ...

Ten years after the first detection of gravitational waves, scientists have captured the clearest signal yet — and it confirms one of Stephen Hawking’s most famous predictions. Using the upgraded LIGO ...

A signal lasting less than a second traveled about 1.3 billion light years before it reached an observatory deep in the piney woods of Livingston 10 years ago. The brief signal — caused by a pair of ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

Scientists say they detected the largest-ever merger of two black holes, forming one that is 225 times the mass of the sun, adding that the new discovery "pushes the limits of" how astronomers ...

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 ...

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO ...

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 ...
