The active galactic nucleus is powered by a supermassive black hole and was spotted just 670 million years after the Big Bang, making it the most distant quasar ever discovered.
A new study theorizes that black holes made of collapsed universes originate dark matter, and our own universe may look like a black hole to outsiders.
A distant galaxy should have a back hole that is billions of times more massive than the Sun, but it's nowhere to be found. Where is it?
It has taken virtually the entire lifespan of the universe for the light from the 'Web of the Giant' to reach Earth.
“Agents could have free choice to make any action they wanted and no paradox would arise because the events just adjust themselves to remain consistent," said study author Germain Tobar.
Where did the elements that make up our bodies come from? How fast is the universe accelerating? A pair of dead stars, among the weirdest scientists have seen, could point toward the answers.
Two recent studies probed ripples in spacetime from cataclysmic black hole events to reveal light in an implausible place and a mystery object in the cosmos.
Astronomers are trying to figure out whether the star collapsed into a black hole without going supernova, or if it disappeared in a cloud of dust.
Usually, when black holes collide, they create gravitational waves that may be detected from Earth. But now, a flare of light has changed that.
A famed physicist dreamed decades ago that future humans, or aliens, could generate energy from black holes. Now, physicists have experimentally shown that it could one day be possible.
Edward Witten, an influential physicist who developed M-theory, recently started thinking about how to scan the solar system for a primordial black hole.
The "dark" black hole is so close to Earth that you can see the system it's in with the naked eye, and hints that there may be many more hidden black holes in the universe.
