A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of ...

Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals, more ...

This week, among a lot of other important findings, we learned that emperor cichlid fish have gaze sensitivity and dislike it ...

A new data release more than doubles the number of gravitational-wave candidate events—and reveals unexpected complexities of merging black holes ...

In February 2016, physicists announced the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment had detected ...

Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, ...

A new study has found that a hidden bias in galaxy models can skew gravitational-wave measurements of how fast the universe is expanding. That finding complicates one of astronomy’s most promising ...

An intriguing new study argues that current detection methods might be far, far more difficult than they have to be.

A new theoretical study suggests that gravitational waves may leave subtle signatures not in giant detectors, but in the ...

A neutron star and black hole (GW200105) were detected merging along an unusual oval orbit, challenging theories about how ...
