Binary black holes, systems consisting of two black holes in close orbit around each other, synchronize their spins before ...

Thanks to Gaia’s accurate stellar mapping, one of the recently detected black holes has a mass larger than any other known black hole in its class. Its existence casts doubt on current astrophysical ...

Space is already filled with plenty of mysteries, and black holes may be among the strangest. Here are some of the questions ...

Using JWST data, researchers found that some black holes accounted for nearly 10% of their galaxy's stellar mass—far exceeding the 0.01% ratio seen in modern galaxies. The findings challenge ...

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered ...

This is suspected to announce the birth of a stellar-mass black hole either when a massive star dies or when two neutron stars collide and merge. The key to determining what caused EP240408A may ...

Expect the unexpected In this artist’s rendering, a stream of matter trails a white dwarf orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. (Courtesy: ...

Astronomers used Chandra and VLBA to study 16 supermassive black holes, revealing jets that changed direction significantly over millions of years. Stellar-mass black holes form when massive stars ...

NASA has discovered more than 100 stellar-mass black holes in the Milky Way’s Palomar 5 star cluster, which is a startling discovery. Nature Astronomy published this discovery. Researchers have ...

If a run-of-the-mill act of stellar destruction wasn’t behind the black hole’s bizarre behavior ... if it were a low-mass white dwarf, about the same size as Earth, it could be hardy enough ...

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar ...

The black holes rip the stars apart and consume their stellar debris — becoming more massive, Northwestern explained. This increases their gravitational pull and draws them together as they orbit..
