For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer ...

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

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

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

A new study proposes an innovative way to uncover elusive supermassive black hole binaries by tracking subtle, repeating ...

A theoretical study accepted by Physical Review Letters predicts that gravitational waves, the faint ripples in spacetime ...

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

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 ...

Scientists led by Durham University’s Institute for Computational Cosmology ran the huge cosmological simulations that can be used to predict the rate at which gravitational waves caused by collisions ...

PITTSBURGH (KDKA) -- We have another question to answer, and this one has to deal with some very interesting clouds. Ray C. took a picture just outside of Uniontown, Pennsylvania, where you can see ...
