Astronomers are getting closer to finding sources of continuous gravitational waves, thanks to observations of Scorpius X-2, a neutron star accreting matter from a low-mass binary companion. So far, ...

PITTSBURGH (KDKA) -- We have another question to answer, and this one has to deal with some very interesting clouds. Ray C. took a picture just outside of Uniontown, Pennsylvania, where you can see ...

After three years of downtime for crucial upgrades, the world’s gravitational-wave observatories were supposed to restart, more sensitive than ever to the tiniest deformations in spacetime. But ...

Scientists have detected the most massive merger of black holes ever. This titanic collision, "heard" in ripples in spacetime called gravitational waves, involves black holes so massive that it could ...

Scientists' recent detection of low-frequency gravitational waves may shed light on what's causing a constant rumble of ripples in the very fabric of space and time. When you purchase through links on ...

The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no small feat to measure the ...

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe's gravitational wave background—the constant flow of waves that churn through the cosmos, ...

There’s a big debate in cosmology about how fast the universe is currently expanding. The collision of two neutron stars in 2017, seen in an artist's rendering, created both gravitational waves and ...

Decades ago physicists realized that gravitational waves are no mere passing phenomenon. Instead those ripples in space should leave behind permanent marks: a fixed distortion in their wake. So far ...
