Black holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being empty, black holes are chock full of matter that gets squeezed into a teensy space.

Researchers believe the 'ultramassive' black hole is big enough to be the largest of its kind ever detected. Black holes are regions of space where the pull of gravity is so intense that even light ...

Black holes are one of the universe’s most enigmatic phenomena. They defy our understanding of physics, challenging our perceptions of reality with their extraordinary characteristics. As astronomers ...

Astronomers detected a black hole displaced nearly a kiloparsec from the center of a dwarf galaxy 230 million light-years away. Unlike most, it is actively feeding and producing radio jets, making it ...

"This is amongst the top 10 most massive black holes ever discovered, and quite possibly the most massive." About 5 billion light-years away from where you're sitting, in one of the most massive ...

They’re the boogeymen of science fiction, a paradox of science and quite possibly a key to understanding the universe. Scientists have been scrambling to understand the mysterious forces of black ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...

Albert Einstein's theory of gravity, general relativity, may not be the best recipe to describe black holes. New research suggests future images of black holes could be precise enough to allow ...

Some people may worry about being bitten by a snake or spider, but have you ever considered what would happen if a small black hole tried to pass through your body? An article by Professor of Physics ...
