Astrophysicists have found the best evidence yet for a low-frequency “hum” of gravitational waves rippling through the cosmos, based on 15 years’ worth of ultra-precise measurements checking the timing of… Read More
After three years of upgrading and waiting, due in part to the coronavirus pandemic, the Laser Interferometer Gravitational-wave Observatory has officially resumed its hunt for the signatures of crashing black… Read More
Christine Ye, a senior at Eastlake High School in Sammamish, Wash., has won the top award in the nation’s oldest and most prestigious competitions for science students, thanks to her… Read More
Telltale ripples in the fabric of spacetime have revealed the existence of a cosmic object that scientists can’t definitively classify. Whatever it is, the object was engulfed suddenly by a… Read More
Japan’s Kamioka Gravitational-Wave Detector, or KAGRA, is due to start teaming up with similar detectors in Washington state, Louisiana and Italy in December, boosting scientists’ ability to triangulate on the… Read More
Two detections of gravitational waves, separated by a mere 21 minutes, set off a flurry of excitement among astronomers today. Was it a binary black-hole merger? A double observation of… Read More
The Laser Interferometer Gravitational-Wave Observatory, or LIGO, has detected mergers of black holes, and even a couple of neutron star smash-ups. But it hasn’t yet confirmed the signature of a… Read More
Physicists won’t be fooling around on April 1 at the Laser Interferometer Gravitational-Wave Observatory in Washington state and Louisiana, or at the Virgo gravitational-wave detector in Italy. Instead, they’ll all… Read More
Four more mergers of black holes, including the biggest one recorded to date, have been added to a catalog generated by gravitational-wave detectors. The additions were announced today by the… Read More
Black holes are the collapsed stars of the show on “Black Hole Apocalypse,” a two-hour “NOVA” presentation that’s premiering Wednesday on PBS. But the Laser Interferometer Gravitational-Wave Observatory, also known… Read More
For the second year in a row, the journal Science is hailing a discovery sparked by the Laser Interferometer Gravitational-Wave Observatory as the Breakthrough of the Year. Last year, the… Read More
It took months to figure it out, but the scientists in charge of the Laser Interferometer Gravitational-wave Observatory, or LIGO, have confirmed their observations of the most lightweight black hole… Read More
For the first time ever, researchers have recorded the cataclysmic smash-up of two neutron stars by virtue of their gravitational waves as well as their electromagnetic emissions, producing data that could… Read More
Another big announcement about gravitational waves is coming up, and this time the hints point to observations in electromagnetic wavelengths as well — emissions of light that may have come from… Read More
This year’s Nobel Prize for physics is going, unsurprisingly, to three people who represent the hundreds of researchers behind the first direct detection of gravitational waves at the Laser Interferometer Gravitational-wave… Read More
Astronomers have detected their fourth gravitational wave from the merger of two black holes, but this one marks a new milestone. It’s the first wave picked up by the Virgo… Read More
An auditorium erupted in a chorus of “Happy Birthday to You” followed by traditional cheers of the English “Hip Hip Hooray” on Sunday at a 75th-birthday celebration for famed physicist… Read More
The Laser Interferometer Gravitational-wave Observatory has detected its third confirmed black hole merger, and this one’s a doozy: LIGO’s latest discovery is about 3 billion light-years away, which is more than… Read More
The Laser Interferometer Gravitational-wave Observatory is back on the hunt for ripples in spacetime, months after reporting the first signature of a black hole collision in gravitational waves. After a series of… Read More
This year’s revelations about gravitational waves are certain to win someone a Nobel Prize someday, but an even richer prize has already been awarded to the scientists behind the Laser Interferometer… Read More
Tim Blais, the singing scientist behind “Bohemian Gravity,” “Rolling in the Higgs” and “The Surface of Light,” is back with another pop parody that’s packed with physics. And this time it’s… Read More
British physicist Stephen Hawking says the detection of gravitational waves provides a completely new way of looking at the universe, and is at least as important as the detection of… Read More
