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.
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.
Scientists didn't even know how to look for this type of black hole until now, thanks to a new study.
The explosion stretched for hundreds of thousands of light years into space and “must have been a bit like a lighthouse beam,” researchers say in a new study.
This alternate explanation for 'Planet Nine,' proposed by scientists in a new paper, poses some fundamental questions like: Should we visit it?
“This is the strongest evidence yet found for such a triple system of actively feeding supermassive black holes.”
“If it turns out to be right, then we’ve confirmed a new type of star system. It’s that fundamental.”
