Before merging, both black holes were spinning exceptionally fast, and their masses fell into a range that should be very rare — or impossible.

Can we classify merging black holes? Astronomers think that such light-swallowing monsters can be classified. Analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration, they show that ...

For just one-tenth of a second in May 2019, the universe delivered a signal that did not fit the usual script. LIGO and Virgo recorded a gravitational wave from GW190521, but unlike the familiar ...

The binary black holes in the universe are already astonishing enough, but researchers from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences have made a groundbreaking ...

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three ...

"Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of black hole binaries." When you purchase through links on our site, we may earn ...

Designed to hunt for new alien worlds, NASA's Transiting Exoplanet Survey Satellite (TESS) has serendipitously observed the rising outburst of a black hole X-ray binary known as AT 2019wey. The ...

"Its special properties make the galaxy an ideal candidate for further research into merging black holes and the associated gravitational waves." When you purchase through links on our site, we may ...

They pull us in, literally and figuratively. Black holes — remnants of collapsed stars — have immense mass that curves spacetime so all paths lead inward. They also capture the popular imagination as ...

Supercomputer simulations are helping scientists sharpen their understanding about the environment beyond a black hole’s ‘shadow,’ material just outside its event horizon. The first black hole images ...
