Black Hole

Astronomers have discovered one of the smallest black holes to date, sitting just 1,500 light-years away which also makes it the closest one to Earth found so far. And they have called it "the Unicorn." The black hole was given the nickname in part because it's so rare but also because…

In this frame from a new visualization, a supermassive black hole weighing 200 million solar masses lies in the foreground. Its gravity distorts light from the accretion disk of a smaller companion black hole almost directly behind it, creating this surreal view. Different colors for the accretion disks make it…

A new NASA visualization traces how the black holes distort and redirect light emanating from an accretion disk. It shows a hypnotic dance of a pair of orbiting black holes. These black holes have mass as same as the millions of times the Sun’s mass. Among two black holes, a…

“If you jump onto and then down from a carousel, you can steal energy from the carousel,” says co-author Salvatore Vitale. “These bosons do the same thing to a black hole.” Credit: Jose-Luis Olivares, MIT Certain ultralight bosons would be expected to put the brakes on black holes, but new…

A pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas -- called an accretion disk -- that surrounds each…
