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.
Milky Way’s Black Hole Just Lit Up in a Way We’ve Never Seen Before
Astronomers have detected a mid-infrared flare from the supermassive black hole at the heart of the Milky Way galaxy for the very first time, and it’s shedding new light on the complex physics driving these energetic outbursts.
New research suggests more supermassive black holes than we ever knew
