A strange chirp detected by LIGO in 2019 has some scientists searching for answers beyond a simple black hole merger.

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were ...

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 ...

Two black holes in deep space. (The SXS [Simulating eXtreme Spacetimes] Project via LIGO/Caltech) (CN) — A merger of two black holes “ring” in the cosmos, producing ripples in the spacetime continuum, ...

An artist's impression of GW250114, a powerful collision between two black holes observed by astronomers in unprecedented detail. - Aurore Simonnet (SSU/EdEon)/LVK/URI Astronomers have detected a ...

Astronomers had long suspected that certain quasars—those brilliant, otherworldly light sources fueled by supermassive black ...

This is the first confirmed case of a star that survived an encounter with a supermassive black hole and came back for more. This discovery upends conventional wisdom about such tidal disruption ...

A decade ago, scientists first detected ripples in the fabric of space-time, called gravitational waves, from the collision of two black holes. Now, thanks to improved technology and a bit of luck, a ...

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 ...

The oldest and most distant black hole known to scientists dates back 13.3 billion years ago, when our universe was still in its teething stage, according to findings published this month. The ...

Christopher Nolan’s Interstellar was a phenomenon in 2014. Set in the future, Earth has been struck by a global crop blight. Former NASA pilot... Why 'Interstellar' has the most accurate black hole in ...
