An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as ...

A group of Manitoba researchers were involved behind the scenes of an international effort that this week revealed the first ...

The merger wasn’t just the biggest ever, but also an event so rare that it challenges existing models for black hole genesis.

At 225 solar masses, this gargantuan merger of two black holes challenges our thinking on these famously elusive objects.

Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One ...

A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole ...

The LIGO Hanford Observatory near the Tri-Cities and its twin in Louisiana detected ripples of time and space passing through ...

And LIGO’s second gravitational wave event, GW151226, is great for both! Essentially, on the pessimist’s side, GW151226 makes it all-but-certain that LIGO is picking up genuine gravitational ...

There are two LIGO detectors. One is in Louisiana (only 30 minutes from where I live) and the other is in Washington. Other gravitational wave detectors exist on Earth, but they were not ...

May 24 marked the start of O4, the latest gravitational-wave hunting effort of the LIGO-Virgo-KAGRA Collaboration. But only LIGO is fully operational right now.

LIGO’s 20-month observation run 04 will officially start on May 24, and it will later be joined by Virgo and a new Japanese observatory—the Kamioka Gravitational Wave Detector, or KAGRA.

Within three weeks, it spotted its first gravitational wave event. A new era. Entire books could be written about all the steps that LIGO takes to limit the noise that is a constant feature of its ...
