In a historic first, astronomers have detected low-frequency gravitational waves using a galaxy-sized antenna of millisecond pulsars in the Milky Way. When you purchase through links on our site, we ...

Researchers have found the first direct evidence of a “background” of gravitational waves in the universe — a sign that gravitational waves from slowly merging pairs of supermassive black holes, or ...

A 15-year search reveals the first evidence of a cosmic 'gravitational wave background' emitted by ancient, colliding black holes. When you purchase through links on our site, we may earn an affiliate ...

Researchers just announced the discovery of the gravitational wave background. After a 15-year-long study, the scientists have finally “heard” what they were looking for: the gravitational waves that ...

Cosmic claims: researchers have used radio telescopes around the world to hunt for gravitational waves using the subtle variations in the timing of pulsars. (Courtesy: Aurore Simonnet for the NANOGrav ...

Ripples in space and time constantly churn through the universe, forming what's called the "gravitational wave background." A new study examines why these waves are so much bigger than scientists once ...

Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB. There’s a new cosmological background in town. In June, researchers from the ...
