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 ...

A faint hum of gravitational waves rippling across the cosmos is now telling scientists what no telescope could show them: the dense, hidden structures buried at the centers of galaxies. A team of ...

A subtle gravitational-wave “hum” from merging black holes may help settle the cosmic fight over how fast the universe is ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea, but it’s believed that gentle ripples should also pervade the universe. Now, a 13-year survey of light from ...

Astronomers just discovered a background “hum” of low-frequency gravitational waves constantly rippling through the universe — but what’s next? When two galaxies merge, the supermassive black holes at ...

Astrophysicists propose a new “stochastic siren” method using the gravitational-wave background from black hole mergers to ...

Scientists have detected a persistent background hum of gravitational waves. This cosmic hum is a new way to explore the ...
