Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black ...

The Earth-Moon system could serve as a natural gravitational-wave detector, using decades of extraordinarily precise lunar laser-ranging measurements to search for tiny orbital disturbances caused by ...

Since gravitational waves were first detected, in 2015, physicists have found almost 400 of these undulations in the fabric of spacetime. A new catalog of the findings, released this year, includes ...

1.3 billion years ago, two orbiting massive black holes, circling each other at 250 times a second, collided in a violent, ...

Current gravitational-wave observatories aren't sensitive enough to capture the gravitational waves of binary stars. They can ...

Beneath the explosions, collisions and other intermittent bangs in the cosmos, scientists suspect a nonstop soundtrack plays, created by ripples in spacetime continually washing through the universe.

When black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

Observations of gravitational waves from merging black holes may unveil the true nature of dark matter, according to new research. The announcement last week of the discovery of the gravitational wave ...

Following 15 years of data collection in a galaxy-sized experiment, scientists have "heard" the perpetual chorus of gravitational waves rippling through our universe for the first time—and it's louder ...
