Black holes — remnants of collapsed stars — have immense mass that curves spacetime so all paths lead inward. They also ...

A tiny black hole zipping through your body sounds like the kind of death dreamed up by a pulp-era sci-fi writer. Which, fittingly enough, it was. In 1974, Larry Niven imagined a murder carried out by ...

New research suggests future images of black holes could be precise enough to allow scientists to determine if these objects are accurately described by Albert Einstein's theory of gravity, general ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...

What would a human see and feel while falling into a black hole? In this exclusive excerpt of his new book, "Facing Infinity," author and astrophysicist Jonas Enander tells us in terrifying detail.

NEW YORK (AP) — Scientists have spotted the brightest flare yet from a supermassive black hole that shines with the light of 10 trillion suns. These bursts of light and energy can come from things ...

This artist's concept depicts a supermassive black hole in the process of shredding a massive star—at least 30 times the mass of our Sun—to pieces. Scientists propose this is what happened around the ...

A supermassive black hole violently gobbled up an enormous star, producing a cosmic outburst with the light of 10 trillion suns, according to a new study. The black hole flare, as the phenomenon is ...
