These include well-known stellar-mass systems like Cygnus X ... astronomers have pieced together a general model of black holes. Surrounding a black hole is often a torus — a donut-shaped ...

Packing all of that bulk—many times the mass of our own sun—into such a tiny point gives black holes their powerful gravitational pull. Thousands of these stellar-mass black holes may lurk ...

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

If a run-of-the-mill act of stellar destruction ... slowly spiraling into the black hole instead of just being gobbled up whole.” Nevertheless, this model remains at best an educated guess.

"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 ...

In the sky, Gaia BH3 is located about 2,000 light years away in the constellation Aquila and appears to be a passive black ...

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 ...

But detections of gravitational waves —- perturbations of spacetime itself —- are one of the few ways to track both the mergers of massive stellar black holes and potentially even massive ...

Theoretical models of stars suggest that the compactness of stellar cores does not increase ... They began by constructing a population model for black hole binary component masses including ...

"This discovery challenges the common belief that black holes formed in star clusters always have randomly distributed spins." ...

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: ...

WASHINGTON, Jan 14 (Reuters) - Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be ...
