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.

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

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.

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,

Black holes themselves emit no light, but the supermassive black holes at the centers of galaxies are often surrounded by huge clouds of material. It's this material, heated by friction and gravity as it swirls in orbit around the black hole, that blazes with light.

Researchers found far more hidden black holes than previously known, indicating plenty of behemoths lurking in 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.
