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

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) ...

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 ...

Since it turned on, the James Webb Space Telescope has revealed dozens of mysterious red blobs in space. The so-called Little ...

Supermassive black holes, often considered the universe's most extreme objects, are now seen as cosmic predators that can slow star growth in galaxies millions of light-years ...

As two supermassive black holes orbit toward each other, they send out gravitational waves that go from lower to higher ...

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

Astronomers propose that instead of a black hole, another dark object could be dominating the Milky Way's center.

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.

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.

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

Scientists believe that when galaxies collide and merge, the supermassive black holes at their centers should eventually pair ...
