Astronomers directly measured the power of jets from black hole Cygnus X-1, confirming decade-old UW–Madison predictions ...

What are the little red dots discovered by the James Webb Space Telescope? These X-rays may offer a clue.

Researchers from Bar-Ilan University have successfully recreated key features of black hole physics in a laboratory setting ...

Hole-y guacamole. Scientists have quantified the energy produced by the first black hole ever discovered, revealing that it ...

Scientists have captured stunning new insights into one of the universe’s most powerful phenomena—black hole jets—by using a planet-sized network of radio telescopes. Focusing on Cygnus X-1, one of ...

We experience three dimensions of space and one of time—four dimensions in total,” study co-author Richard Pinčák, of the ...

Scientists have traced a 3,000-light-year-long cosmic jet streaming out from the first black hole ever imaged to its likely source point with the help of "significantly enhanced coverage" from the ...

A nearby active galaxy called VV 340a offers a dramatic look at how a supermassive black hole can reshape its entire host. Astronomers observed a relatively weak but restless jet blasting outward from ...

In 1974, a brilliant 32-year-old physicist published a not-quite-two-page paper in the journal Nature — and blew up one of our fundamental assumptions about black holes. The author was Stephen Hawking ...

An unusually massive black hole in the very early universe may be a kind of exotic, star-less black hole first theorised by Stephen Hawking. In August, Boyuan Liu at the University of Cambridge and ...
