The Hubble and Chandra space telescopes are hunting for rogue black holes wandering through dwarf galaxies, which could ...

If a pair of black holes coalesce into one, much of that vast energy can be released in a few seconds.

Scientists have long suspected that active supermassive black holes can kill their own host galaxies, but new research suggests these cosmic titans are more like serial killers that can extend their ...

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies ...

Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our ...

New research reveals that active supermassive black holes can halt star formation in neighboring galaxies, acting like cosmic serial killers across millions of light-years.

Scientists have named two systems of colliding supermassive black holes after Lord of the Rings locations, Gondor and Rohan.

An exotic type of dark matter could explain some of the characteristics of our galaxy’s central supermassive black hole, but many cosmologists are leery of the idea ...

In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.

NASA compares the universe's biggest black holes with "each other and to our solar system," in this Goddard Space Flight ...

Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...
