The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from ...

Astronomers discover two giant black holes set to collide in 100 years and detect key signals from Markarian 501.

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can ...

A black hole isn’t actually a hole at all; it’s an incredibly dense object where a huge amount of matter is squeezed into a tiny space. Its gravity is so strong that once anything gets too close, not ...

Shock waves from tiny black holes in the early universe could explain how antimatter became so rare while matter is common.

What are the little red dots discovered by the James Webb Space Telescope? These X-rays may offer a clue.

Nearly every galaxy has a supermassive black hole in its core. Whether the black hole forms first and then the galaxy around it—or the other way around—is still a matter of some debate, but we know ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

Nearly all massive galaxies are known to host central black holes. And dwarf galaxies can indeed also host central black holes, but whether all or only a fraction of them do remains an open question ...

In the Black Hole Symphony, composer David R. Ibbett tries to translate one of the universe’s brightest observable objects into music.
