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.

In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If sufficient mass could be placed into an ...

A gravitational wave signal recorded by the LIGO, Virgo, and KAGRA detectors on November 12, 2025, has drawn intense ...

Primordial black holes are ancient mysteries, born in the universe’s earliest seconds. Unlike regular black holes, they weren’t formed by collapsing stars. Instead, they emerged when extremely dense ...

BUFFALO, N.Y. — Imagine the formation of a black hole and you’ll probably envision a massive star running out of fuel and collapsing in on itself. Yet the chaotic conditions of the early universe may ...

A view of the central region of the Perseus galaxy cluster, one of the most massive objects in the universe, shows the ...

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...

Explore black hole discovery in astrophysics, from hidden stellar remnants to supermassive giants, and learn how scientists detect these invisible cosmic objects using light and gravitational waves.

Why they're black: Their gravitational pull is so extreme that even light can't escape Black holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being ...
