Past research about black hole births rarely included magnetic fields or the spins of the precursor stars. But considering ...

Scientists may have solved the mystery of an "impossible" merger between two black holes so massive and fast-spinning that ...

For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287. Roughly twice every 12 years, from 3.5 billion light years away, the light ...

Virgo-KAGRA collaboration. Their detectors captured the gravitational waves created by the violent crash of two immense black ...

(CNN) — Astronomers have detected a collision between two black holes in unprecedented detail, offering the clearest view yet into the nature of these cosmic oddities and confirming long-held ...

Gravitational waves shake the very fabric of the universe when black holes collide. Today we measure these events and use them to understand the cosmos. Now University of Copenhagen researchers and ...

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 ...

Here’s what you’ll learn when you read this story: Black holes usually form from stars that burn out and collapse in on themselves, but that cannot explain the red spark of light that could be a ...

Astronomers spotted the largest flare ever released from a supermassive black hole as it snacked on a giant star.

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.
