Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to ...

Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

In the nearby Andromeda Galaxy, a massive star bright enough to stand out for years has gone dark. Not in a blaze of glory.

Astronomers have caught a supermassive black hole doing something that sounds like science fiction: racing through space at roughly 1,600 kilometers per second, based on recent James Webb Space ...

New research reveals how quiet galactic engines can help shape entire galaxies.

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

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

Black holes are often considered terrors of the known universe. Supermassive black holes are regions of space where the pull of gravity is so intense that even light doesn't have enough energy to ...

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

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.

Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black holes crashed into each other billions of light-years away. The result is a ...
