Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very ...

Chandra X-ray Observatory and X-ray Polarimetry Explorer (IXPE) imagery of the Milky Way's core and supermassive black hole Sagittarius A* has been sonified by SYSTEM Sounds. Credit: ...

NASA's newest astronomical instrument, the X-ray Imaging and Spectroscopy Mission (XRISM), launched into orbit last September ...

Supermassive black holes usually lurk unseen, but when an unlucky star drifts too close they ignite titanic outbursts brighter than 100 supernovae. By mixing NASA, ESA, and ground-based data, ...

One of the most perplexing discoveries in modern astronomy has been finding supermassive black holes, some weighing billions of times more than our sun, in galaxies that formed less than 750 ...

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding supermassive black hole.

A distant supermassive black hole has stunned astronomers by expelling matter at speeds nearing a third of light velocity after consuming material at an extreme rate.

Lite intermediate-mass black holes could be the missing link between the well-known populations of stellar and supermassive black holes. Understanding how these middleweights form and where they live ...
