Black Holes

A tiny galaxy orbiting at the outskirts of the Milky Way appears to have a giant black hole at its center, comparable to that of the much larger Milky Way itself, and scientists don't know why.

A little density is effective in fighting back.

A pair of supermassive black holes that will soon become one has been discovered hiding in a nearby galaxy.

Astronomers may have seen the light from two black holes smashing into one another for the first time ever.

Scientists studying cosmic rays near the galaxy's center discovered a strange 'barrier' keeping the fast-moving rays from entering the Milky Way's middle.

In a recent study, researchers determined that about 1% of all the "normal" (that is, not dark) matter in the universe is bound up inside black holes.

The hypothesis could help to explain the weird discrepancies spotted in space-time ripples from enormous black hole collisions.

Finding a black hole isn't straightforward, and it's even harder the more distant such a behemoth is.

Scientists have released the largest catalog of gravitational wave detections to date, shedding new light on interactions of the most massive objects in the universe, black holes and neutron stars.

The first (and only) black hole to ever have its snapshot taken from Earth shoots out vast jets of plasma that travel near the speed of light, new computer models show.

The newly released astronomy and astrophysics decadal survey flags the discovery and study of habitable exoplanets and the exploration of black holes and neutron stars as two top research priorities.

A new physics breakthrough shows how Einstein's theory of general relativity continues to hold up, even for "balding" black holes.

An ultrabright, ultrafast explosion called the Camel lit up the sky for a month in 2020. Astronomers think it might have been the birth of a black hole or neutron star.

The elements around some giant black holes may be subtly different from the cosmic average, retaining a relic memory of the young universe.

Plumes of hot gas and charged particles emitted by black holes drift across distances of hundreds of thousands of light years.

Black holes exert small amounts of pressure on their environment a new study finds, hinting at a more complex nature of these mysterious objects.

There comes a time in every galaxy's life, astronomers think, when the galaxy ejects a large part of its gas, but scientists aren't certain what drives this "mid-life crisis."

Astronomers have uncovered evidence of explosions triggered by dead stars ramming into live stars, possible proof of a new type of supernova, a new study finds.

What are the chances that a primordial black hole forged in the earliest moments of the universe will come wandering toward Earth?
