Joseph Giaime, head of the observatory, joined Louisiana Considered to talk to us about the event’s significance, and how ...

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

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

A strophysicists have discovered the largest known merger of two black holes to form a larger single hole about 225 times the mass of the sun. The violent collision between the spinning objects, one ...

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 ...

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

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 ...

A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics ...

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.

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 ...

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.
