Images taken of the Universe's most photogenic black hole over time reveal strange and exciting changes in its magnetic field. Using observations obtained using the Event Horizon Telescope in 2017, ...

An artist's impression of GW250114, a powerful collision between two black holes observed by astronomers in unprecedented detail. - Aurore Simonnet (SSU/EdEon)/LVK/URI Astronomers have detected a ...

In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.

The magnetic field swirling around an enormous black hole, located about 55 million light-years from Earth, has unexpectedly switched directions. This dramatic reversal challenges theories of black ...

Listen to more stories on the Noa app. To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in ...

The last gasp of a primordial black hole may be the source of the highest-energy "ghost particle" detected to date, a new MIT study proposes. In a paper appearing today in Physical Review Letters, MIT ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...

A black hole with an extraordinary appetite, consuming the equivalent of 3,000 Suns every year, has left scientists both baffled and terrified. Its growth rate, which is a staggering 2.4 times faster ...

One of the first black holes ever imaged is even stranger than we thought, new images of its dramatically changing environment reveal. The object, known as M87*, has experienced unexpected changes in ...

A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA's Chandra X-ray Observatory may help explain how some black holes can ...

Supermassive black holes may not be as massive as previously thought, according to a new discovery by scientists. Astronomers from the University of Southampton, working with colleagues from France, ...
