Blazar galaxy Marakarian 501 has a supermassive black hole at its center. This black hole shoots out powerful, fast light. But how?

About 99 percent of all the mass released in a tidal disruption event is called nonrelativistic—it moves along at 10 percent the speed of light or less. The remaining 1 percent, however, is very ...

A supermassive black hole in the center of the Milky Way galaxy is creating a light show that's intriguing astronomers. Flares of light have been observed in a disk orbiting the black hole ...

In 2019, the same team captured an image of the black hole in the galaxy Messier 87, or M87. That image, the first ever taken of a black hole, is now enshrined in the Museum of Modern Art in New York.

The giant black hole has a mass of 30 billion suns and sits at the center of a galaxy located hundreds of millions of light-years from Earth. Astronomers call the cosmic monster an ultramassive ...

A black hole formed from electromagnetic energy — that is, light — is called a kugelblitz. That concept has been jangling around in physicists’ brains for decades.

Back in May, Harvard researchers released the first-ever photograph of Sagittarius A*, a black hole which sits at the core of the Milky Way. Sagittarius A* is about 26,000 light-years from earth.

Now, the particulars of how light around M87’s black hole is oriented could rule out the likelihood of axion particles in a specific mass range, researchers report March 17 in Nature Astronomy.
