Astronomers and astrophysicists at five different pulsar timing array collaborations today announced data that strongly suggests the presence of a gravitational wave background: a constant murmur of ...

Scientists may have "heard" the first tantalizing evidence of primordial black holes formed directly from overly dense ...

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 ...

Astronomers may have seen the light from two black holes smashing into one another for the first time ever. Black holes are completely dark and therefore invisible to light-detecting telescopes. So ...

Scientists are still hunting for the source of the faint, persistent hum of gravitational waves discovered reverberating through the Milky Way last year. Those waves could point to more than one ...

A new breakthrough in gravitational wave research is challenging long-standing assumptions about how these signals behave.

After a three-year hiatus made longer by pandemic troubles, the search for gravitational waves — ripples in space-time that are the hallmarks of colliding black holes and other cosmic cataclysms — has ...

Astrophysicists describe what galaxy-wide gravitational waves could mean for our understanding of black holes and the history of the cosmos. Gravitational waves are ripples in the fabric of space-time ...

EVANSTON, Ill. (CBS) -- A Northwestern University astrophysicist is part of an international team of scientists creating a gravitational wave detector system that will eventually be launched into ...

Editor’s Note: Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. Astronomers have been able to “hear” the ...

It sounds like the setup for a joke: If radio waves give you radar and sound gives you sonar, what do gravitational waves get you? The answer might be “GRADAR” — gravitational wave “radar” — a ...

This week in the journal Nature Communications, a group of scientists describe a new robot they're working on — with funding from NASA's Jet Propulsion Laboratory — inspired by the way animals use ...
