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

Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten ...

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

Back in May, Hagerty contributor and AMC aficionado Joe Ligo penned the story, “Do ‘Cheap’ AMC Cars Still Exist? Kind Of…” In ...

The largest black hole collision ever recorded has scientists' jaws on the floor — and scratching their heads.

LIGO-Virgo/Frank Elavsky, Aaron Geller/Northwestern The LIGO Scientific Collaboration and Virgo Collaboration released a catalog of results from the first half of its third observing run (O3a). This ...

That tiny time shift, arising from the fact that LIGO's (and Virgo's, and KAGRA's) arms compress by about 0.01% the width of a proton, is presently being used to find dozens of new merger events ...

For now, the LIGO team cannot localize where these black holes merge. But as more detectors come online in Europe, Japan and India, researchers will be better able to triangulate the sources.

LIGO’s analysts worked for months to verify the first detection as well as the December event. The September event turned out to be the focus of February’s announcement.

LIGO detected gravitational waves created from the collision between two black holes. The detection was awesome, but let's look at the name of the detector for a second: Laser Interferometer ...

When LIGO detected gravitational waves for the first time, we were delighted, but we weren't surprised. Theorists had calculated exactly the type of LIGO-sensitive signal that should result from ...

Meanwhile, the LIGO team analyzed the data, determining that the signal was legit. A comparison with the normal background noise of the detector suggests that a signal like this will only show up ...
