A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

New details have been discovered about M87*, the first black hole ever photographed, revealing its plasma, its brightness and ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Black holes and their archaeology The results of the SDSS Survey of mass measurements of hundreds of black holes were a surprise, according to Fries. That's because the spin rates reveal something ...

Using the Gemini North telescope, astronomers have detected the largest black hole jet ever seen in the early universe. It's twice as long as the Milky Way.

Gravitational waves are unlocking the origins of black holes, linking spin shifts to sequential mergers in star clusters.

"Unexpectedly, we found that they were spinning too fast to have been formed by galaxy mergers alone. "They must have formed in large part from material falling in, growing the black hole smoothly ...
