Physicists have detected the biggest ever merger of colliding black holes. The discovery has major implications for researchers’ understanding of how such bodies grow in the Universe. “It’s super ...

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 ...

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 ...

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new ...

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 ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...

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-funded (NSF) LIGO ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...

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 ...
