On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...

After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...

Scientists on the lookout for subtle disturbances in the fabric of space-time have detected the signal from a cataclysmic collision between two black holes that lie some 3 billion light-years away, ...

Speculation is running rampant about potential new discoveries of gravitational waves, just as the latest search wound down August 25. Publicly available logs from astronomical observatories indicate ...

After a year of downtime to perform hardware upgrades, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is ready for action and will turn on its twin detectors, one in Washington state ...

The LIGO Scientific Collaboration and Virgo Collaboration released a catalog of results from the first half of its third observing run (O3a), and scientists have detected more than three times as many ...

The journey began about 20 years ago. The Laser Interferometer Gravitational Wave Observatory (LIGO) was built in Handford, Washington, and Livingston, Louisiana, to detect and study the gravitational ...
