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 ...

Astronomers have uncovered a gargantuan black hole that appears to sit almost alone in space, with hardly any stars around it ...

QSO1. It lived just 700 million years after the Big Bang and already had a mass about 50 million times that of the Sun.

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 ...

Two nearby black holes were discovered using precise star position data. These black holes are unique because they don't actively pull in nearby matter. Radio wave observations confirmed the lack of ...

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a ...

Astronomers have spotted a mysterious cosmic object that could be the lightest black hole or the heaviest neutron star ever discovered — or something completely new to science. The unknown object, ...

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 ...

Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with ...
