Black holes are points in space that are so dense ... While the star was alive, nuclear fusion created a constant outward push that balanced the inward pull of gravity from the star's own mass.

An experimental setup mimics a “black hole bomb” first theorized in 1971. The spinning cylinder with circuitry is true to the ...

Scientists have made the most accurate predictions yet of the gravitational waves produced when two black holes fly past each ...

Researchers have discovered that ultra-fast wind surrounding a supermassive black hole is not smooth and continuous as ...

A study published in Nature has established a new benchmark in modeling the universe's most extreme events: the collisions of ...

Another kind of supernova is called type I. That happens when two stars orbit each other. One star may start siphoning the ...

The black hole now gives off powerful X-rays at nearly regular intervals. These outbursts are known as quasi-periodic eruptions (QPEs), and have been observed emitting from other black holes. But ...

While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared. An enormous black hole in the ...

After decades of inactivity, the black hole at the galaxy's heart burst with light. Now, the cosmic monster appears to be doing something that is forcing astronomers to re-evaluate their ...
