Black holes spin in captivating embrace in stunning new simulation imagery - Binary black holes move in tandem before merging ...

For astronomers, finding a new black hole orbiting an aged red dwarf star is an exciting find in itself, but when that black ...

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

"They are everywhere!" A terrifying finding made in a solar system void. The discovery of a record-mass stellar black hole in our galaxy.

Its formation and survival in this extreme environment mean that black holes are not as destructive as previously thought. The discovery of the young binary star now shows that even stellar pairs can ...

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

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into ...

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.

"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 ...

If a run-of-the-mill act of stellar ... system—perhaps, for instance, the radio flares, giant jets and x-ray pulses all instead trace back to poorly understood interactions between the 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 ...
