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

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

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 ...

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 ...

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 ...

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.

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.

Researchers propose a new technique to identify supermassive black hole binaries through gravitational lensing causing ...

Many of us remember all too well our childhood bout of chickenpox: those itchy, scabby, red spots that appeared all over our ...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile have discovered "signs of a ‘hot spot’ orbiting Sagittarius A*," according to the European Southern Observatory (ESO) ...
