A balloon-borne telescope has captured one of the most precise glimpses yet of the chaotic environment around a black hole. Suspended in the upper atmosphere, the experiment focused on Cygnus X-1, a ...

For decades, scientists have suspected that some quasars, which are regarded as some of the brightest objects in the universe, might actually conceal not one but two black holes locked in a ...

When scientists discovered an enormous black hole thousands of light-years from where it ought to be in space, they knew they had a cosmic oddity on their hands. NASA's Hubble Space Telescope showed a ...

A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth. The burst, called ...

For the first time, astronomers have managed to capture a radio image showing two black holes orbiting each other. The observation confirmed the existence of black hole pairs. In the past, astronomers ...

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, ...

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

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.

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 ...

Here’s what you’ll learn when you read this story: Black holes usually form from stars that burn out and collapse in on themselves, but that cannot explain the red spark of light that could be a ...

The younger black hole, the product of a cataclysmic cosmic event known as a black hole merger, was first spotted in 2019. Now, about 6 years later, a team of international researchers led by the ...
