Past research about black hole births rarely included magnetic fields or the spins of the precursor stars. But considering ...

Sharper views of black holes are turning what once looked like a fuzzy cosmic icon into a precision tool for testing gravity ...

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 ...

An international collaboration of physicists including researchers at Washington University in St. Louis has made measurements to better understand how matter falls into black holes and how enormous ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful ...

Monster black holes entered the cosmic scene soon after the Universe’s birth and grew rapidly, reaching millions or even ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion ...

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 ...

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed ...

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 ...
