"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed ...

A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth. The burst, called ...

A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered ...

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.

Astronomers have discovered what could be the largest black hole ever detected. With a mass of 36 billion times that of our Sun, its gravity is so powerful that it bends the light of an entire galaxy ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

Something unusual may have risen from the ashes of an epic smashup. In the middle of a galaxy shaped like an infinity symbol — thought to be the result of two galaxies colliding — sits a supermassive ...

Interstellar black hole with glowing accretion disk and singularity nucleus. Concept 3D animation of cosmic wormhole on starry space background. Theory of relativity and quantum physics wallpaper.

When black holes emerge out of hiding to feast on their prey and some type of matter is sucked into their celestial maw, they begin to glow brightly. The events, dubbed “extreme nuclear transients,” ...
