Researchers have identified a rogue black hole, marking the first time such an isolated object has been confirmed in deep ...

While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared. An enormous black hole in the ...

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and ...

Black holes, the densest objects in the universe, eat up anything that comes too close, even light. Is there anything left inside these behemoths that could reveal what they devoured in the first ...

What if everything we know—the stars, the galaxies, the expanding fabric of space-time—isn’t floating in a limitless void, but instead exists inside a black hole? It may sound like a work of ...

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense X-ray flares at regular intervals that have puzzled scientists, a study said Friday.

They suggested it might be a lone black hole. Shortly thereafter, a second research team challenged that result, suggesting it was more likely a neutron star. After continuing to study the object ...

Dark matter may have contributed to the formation of giant black holes in the early universe, researchers propose in a new paper. More observations, especially with the James Webb Space Telescope ...

The lone black hole without a companion star is located 5,000 light-years away. A team of scientists have confirmed the existence of a lone black hole that has no star orbiting it in the Milky Way ...

The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

This artist’s impression illustrates the mechanism that could be at the origin of the powerful bursts of X-ray light seen from a newly awakened black hole named Ansky. ESA; ACKNOWLEDGEMENTS ...
