The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

On May 21, 2019, a ripple in the fabric of spacetime swept over Earth at the speed of light. These pass through us all the time, but this one was strong enough to warp space noticeably, at least to ...

Researchers from the UAB, IFAE and University College London propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, ...

Researchers propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, as a new gravitational wave detector within a ...

Gravitational-wave observatories have released their latest catalogue of cosmic collisions, bringing their total number of detections to 90. The new crop of 35 events includes one featuring the ...

Europe’s gravitational-wave hunters are celebrating. On 1 July, a satellite will wrap up its mission to test technology for the pioneering quest to measure gravitational ripples in the stillness of ...

It sounds like the setup for a joke: If radio waves give you radar and sound gives you sonar, what do gravitational waves get you? The answer might be “GRADAR” — gravitational wave “radar” — a ...
