Black holes are spinning faster than expected, researchers find
There's a universe full of black holes out there, spinning merrily away—some fast, others more slowly. A recent survey of supermassive black holes reveals that their spin rates reveal something about their formation history.
Supermassive Black Hole Caught Doing Something Never Seen Before
Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which means we have a front row seat to small-scale black hole behavior that would be too faint to see were it taking place in another galaxy.
Mysterious flashing seen near supermassive black hole. Astronomers have an idea what it is
A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?
Black holes differ in mass and spin: May have formed in different ways
Gravitational wave observations have revolutionized our understanding of black holes, revealing crucial details about their masses and spins. These measurements, collected from binary black hole mergers,
Infrared telescopes discover hundreds of previously undetected supermassive black holes
Using IRAS and NuSTAR telescopes, scientists identify hundreds of obscured black holes hidden behind gas and dust.
Unprecedented View of a Supermassive Black Hole in Action
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, o
