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

New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the ...

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 ...

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

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 ...

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

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

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.

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 ...

Scientists have named newly detected merging supermassive black holes after ’Lord of the Rings’ locations, using gravitational wave data and quasar observations to map their mergers.

Webb telescope data confirm a supermassive black hole fleeing its galaxy, carving a 200,000 light-year wake of new stars.

For a single supermassive black hole, extremely strong lensing occurs only when a star lies almost exactly along the line of ...
