Black holes
Black holes are regions of space where the gravitational pull is so strong that nothing — not even light — can escape. Rather than empty space, black holes are chock full of matter that gets squeezed into a teensy space.
Latest about Black Holes

An ancient, ravenous black hole has been hiding an 11-billion-year-old galaxy in its glare
By Robert Lea published
A team of astronomers has used a tricky technique to study an ancient galaxy previously lost in the glare of a blazing quasar.

New Horizon Prize in Physics awarded to scientists chasing mysterious black hole photon spheres
By Ben Turner published
Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity.

The closest black holes to Earth may be lurking in a star cluster visible to the naked eye
By Brandon Specktor published
Astronomers found evidence of multiple stellar-mass black holes lurking in the nearby Hyades cluster, just 150 light-years from Earth.

For the 1st time, scientists accidentally measure the swirling ring around a black hole
By Harry Baker published
Researchers accidentally stumbled on a way to measure the size of the accretion disks of dust, gas and plasma that surround black holes.

Do black holes really suck in matter?
By Robert Lea published
Black holes can swallow matter, and they grow by accreting gas, dust and even the occasional star. But are they the vacuum-mouthed monsters they are often presented to be?

Black holes keep 'burping up' stars they destroyed years earlier, and astronomers don't know why
By Robert Lea published
Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.

James Webb telescope reveals the universe may have far fewer active black holes than we thought
By Briley Lewis published
Almost every galaxy in the universe has a supermassive black hole at its center. So why is it so hard to find young black holes actively feeding?

'Twisty' new theory of gravity says information can escape black holes after all
By Paul Sutter published
Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'
