When a supermassive black hole in a nearby galaxy suddenly brightened in X-rays, astronomers watched it do something they had ...

Astronomers have made a groundbreaking discovery by catching a supermassive black hole “in the act” of awakening, located in the galaxy cluster CHIPS 1911+4455, which is an astounding 6 billion ...

The most massive stars in the universe are destined to explode as brilliant supernova before collapsing into black holes. Yet one huge star appears to have never fulfilled its destiny; in a twist of ...

When black holes emerge out of hiding to feast on their prey and some type of matter is sucked into their celestial maw, they begin to glow brightly. The events, dubbed “extreme nuclear transients,” ...

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 ...

A space telescope and AI teamed up to analyze a million galaxies and learn what triggers supermassive black holes the most.

Astronomers have detected the first tidal disruption event (TDE), designated AT2024tvd, occurring 2,600 light-years outside its host galaxy's core, exhibiting intense, rapidly evolving radio signals.

Here is what you will learn when you read this story: Little red dots (LRDs) observed by the James Webb Space Telescope were initially thought to be galaxies, but something was amiss. Researchers who ...

Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the "Infinity" galaxy—two recently-collided galaxies that, together, look like the symbol for ...

Primordial black holes that formed during the earliest moments of the universe could have swollen quickly to supermassive sizes, complex cosmological simulations have revealed. The discovery could ...
