Chance encounter: Artist’s impression of the gravitational waves emitted by merging black holes. (Courtesy: LIGO/T Pyle) Astronomers in the US have found strong evidence that a merging pair of black ...

As far as odd couples go, this is one for the record books. The ripples in spacetime stirred up by two distant, merging black holes suggest that one of the pair was much bigger than the other. It’s ...

The Laser Interferometer Gravitational Wave Observatory (LIGO) has seen over 300 black hole mergers in its short time in operation, and now it’s seen an event so large—and so rare—that it challenges ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...

PASADENA, Calif. ― The 2017 Nobel Prize in physics has been awarded to three scientists who played instrumental roles in the first-ever direct detection of gravitational waves, or ripples in the ...

The 2017 Nobel Prize in Physics has been awarded to three key players in the development and ultimate success of the Laser Interferometer Gravitational-wave Observatory (LIGO). One half of the prize ...
