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?
New research suggests more supermassive black holes than we ever knew

NASA Astronomers Zero In on the Number of Hidden Supermassive Black Holes
Researchers found far more hidden black holes than previously known, indicating plenty of behemoths lurking in thick clouds of gas and dust.
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,
