Using the MIRI instrument onboard the James Webb Space Telescope, an international team of scientists made the first-ever detection of a mid-IR flare from Sagittarius A*, the supermassive massive black hole at the heart of the Milky Way.

NASA's Chandra and NuSTAR telescopes have teamed up to study a supermassive black hole-powered quasar that could have played a key role in ending the cosmic dark ages.

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

Active galactic nuclei are supermassive black holes at the center of certain galaxies. As matter falls into these black holes, enormous amounts of energy are released, making active galactic nuclei, or AGN,

Researchers found far more hidden black holes than previously known, indicating plenty of behemoths lurking in thick clouds of gas and dust.

The universe could be home to far more supermassive black holes than we realised, according to new research. Astronomers from the University of Southampton say that 35% of these galactic giants - some which are billions of times heavier than the sun - have gone undiscovered because they are obscured by thick clouds of gas and dust.

A new study suggests more supermassive black holes may be lurking in the universe than previously thought. Astronomers from the University of Southampton have discovered that 35 per cent of these enormous entities—some of which are billions of times heavier than the sun—remain undetected.
