In a groundbreaking development, scientists have detected the ringing of black holes following a collision event, confirming ...

In January 2025, a ripple in spacetime reached Earth from more than a billion light-years away. It wasn’t light or radio ...

For more than 50 years, scientists have dreamed of seeing the hidden patterns that govern the motion of nonlinear waves—the ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by international pulsar timing array collaborations in 2023 could come from a stochastic ...

In the Crab Nebula, a rapidly rotating neutron star, or pulsar (white dot near the center), powers the dramatic activity seen by Chandra. The inner X-ray ring is thought to be a shock wave that marks ...

On the afternoon of Oct. 9, 1876, Alexander Graham Bell was in Boston when he had a three-hour chat with his assistant and fellow inventor, Thomas Watson. It would not have been noteworthy — except ...

Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...

Ten years ago this month, gravitational waves were first detected on planet Earth. Now, gravitational waves had been something that scientists had thought existed going back to Albert Einstein. His ...

News from NASA A massive earthquake and subsequent tsunami off Russia in late July tested an experimental detection system that had deployed a critical component just the day before. A recent tsunami ...
