Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 ...

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe. New research may explain how they formed, thanks to primordial "seeds".

For decades, astronomers have puzzled over how the supermassive black holes residing in the center of galaxies form. Now, ...

Scientists may have uncovered how supermassive black holes, forming mere hundreds of millions of years after the Big Bang, ...

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe.

"The results we are obtaining are truly unexpected, and all point to a super Eddington-type growth mechanism for black holes.

Black hole coronae are billions of degrees hot, which makes them a lot more difficult to study in detail. Using NASA’s IXPE ( ...

Black holes don't have many identifying features. They come in one color (black) and one shape (spherical). The main ...

Researchers using XMM-Newton and Chandra telescopes have linked X-ray emissions from 21 distant quasars to rapid supermassive ...

NASA compares the universe's biggest black holes with "each other and to our solar system," in this Goddard Space Flight ...

At a singularity, the laws of physics as we know them suffer a complete breakdown. So such objects really shouldn’t exist.
