New Canadian-led research has peered into the strange world of black holes to discover they're girded by electromagnetic winds that not only influence how the super-dense interstellar bodies gobble up ...

Ultraluminous X-ray sources (ULXs) represent some of the most energetically extreme phenomena in neighbouring galaxies, emitting X‐ray luminosities that can far exceed the Eddington limit. Long ...

This image shows the gas density in a two-dimensional cross-section of an accreting black hole. Brighter areas represent regions of higher density. Near the black hole, the accretion flow forms a ...

Astronomers have detected a repeating 20-day signal from two distant black hole systems, aligning with predictions from Einstein’s general theory of relativity. In ASASSN 14ko, the cycle is linked to ...

Although we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, their very nature makes them difficult to spot and study. In contrast to the ...

A global team of astronomers has produced the first image that captures both the glowing ring of matter around a supermassive ...

A supermassive black hole in the center of the Milky Way galaxy is creating a light show that’s intriguing astronomers. Flares of light have been observed in a disk orbiting the black hole Sagittarius ...

What happens when a gargantuan cloud of gas swallows a pair of monster black holes with their own appetites? Feasting on the gas can cause some weird (heavenly) bodily functions. AT 2021hdr is a ...
