Identifying the gravitational waves from black holes binaries could also make it clearer to detect primordial gravitational waves that date back to inflation at the moment of the Big Bang.
After decades of searching, astronomers have imaged two supermassive black holes in orbit around each other at the heart of quasar OJ287.
Newly released images of the supermassive black hole at the heart of the galaxy M87 show that the plasma that swirls around it has unexpectedly reversed directions.
The mystery of the James Webb Space Telescope's "little red dots" could be solved if they are not ancient galaxies but are entirely new celestial objects called "black hole stars."
Everything about the Infinity Galaxy, recently discovered by the JWST, is strange. One odd feature could be the first evidence of a "direct collapse" black hole.
Astronomers have discovered a rogue intermediate mass black hole blasting out jets over 3,000 light-years from the heart of its home galaxy, where it would usually lurk.
