After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves - tiny ripples in space itself that travel through the universe. Unlike light ...

Detector engineers Hugh Radkins (foreground) and Betsy Weaver (background) take up positions inside the vacuum system of the detector at LIGO Hanford Observatory to perform the hardware upgrades ...

After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...

It has been three years since the Laser Interferometer Gravitational-Wave Observatory (LIGO) shut down, starting a long hiatus from searching the universe for gravitational waves. Now, though, the ...

LIGO is made up of two observatories that detect gravitational waves by splitting a laser beam and sending it down several mile long tunnels before merging the light waves together again. A passing ...

Researchers detect the clearest black hole signal to date, enabling tests of Hawking's area theorem and advancing ...

The best place to observe the stars is among them, which is why Hubble and the James Webb Space Telescope have been deployed outside Earth's murky atmosphere. At least, that's the case when you're ...

LIVINGSTON, Louisiana—In a large press event today, the scientists behind the LIGO experiment announced the first direct detection of gravitational waves, ripples in the fabric of space-time generated ...

A scientific collaboration that includes physicists from William & Mary announced that three detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. It’s ...

Scientists have announced the fourth discovery of gravitational waves produced by the collision of two black holes — and it’s the first such smash-up found with the help of the European Virgo detector ...

The recent detection of gravitational waves did more than just confirm Einstein's theory of relativity; it provided our first direct observational evidence of the existence of black holes. That ...
