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 ...

“LIGO has taken great strides, and are moving towards open data and reproducible science,” he says. “But I don’t think they’re quite there yet.” The Danish group’s independent checks, published in ...

This artwork imagines the ultimate front-row seat for GW250114, a powerful collision between two black holes observed in gravitational waves by the US National Science Foundation LIGO. It depicts the ...

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 ...

Could LIGO find alien spacecraft accelerating to near light speed? The gravitational wave detector LIGO has made hugely important discoveries. But what else might be hiding in the ripples’ of ...

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 ...

On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...

Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO. In 2015, ...
