Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this ...

Scientists have observed a new type of black hole that is too heavy to have been born from a star but still too slim to … The ...

The earliest and most distant supermassive black hole discovered thus far by JWST is CEERS 1019, which existed just 570 ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions ...

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding ...

The black hole must also be more massive in order to explain its gravitational tug on such a massive star. The black hole weighs about 21.2 suns — much heftier than its previously estimated 14.8 ...

The mysteries of a very ancient and massive black hole are being unraveled using NASA's James Webb Space Telescope (JWST).. This supermassive black hole, found in the center of a galaxy named ...

The hunt for intermediate-mass black holes (IMBH) has picked up over recent years, and there are now dozens of promising candidates. This artist’s concept depicts a 2,200 solar mass IMBH ...

Astronomers believe they have discovered a supermassive black hole located 700 million light-years from Earth — and it has a mass 40 billion times that of the Sun.

More massive black holes, for example, would need hundreds of days, or possibly years, of observations to reveal their masses. Upcoming observatories are already planning to take that kind of data.

The primordial black hole is around 1 billion times the mass of our sun and was found at the center of the galaxy COS-87259. The ancient galaxy formed just 750 million years after the Big Bang and ...

Stellar-mass black holes — which weigh between a few and 100 times the mass of the Sun — speckle the universe. In our Milky Way alone, there are an estimated ten million to one billion stellar ...
