Supermassive black hole is spinning at half the speed of light, astronomer finds

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) – A supermassive black hole inside a distant quasar spins at about 336 million mph (540 million kph) or roughly half the speed of light, according to research published on Wednesday in the journal Nature. Scientists have measured the spin rates of black…

Watch: Milky Way’s supermassive black hole is killing a ginormous gas cloud

Supermassive black hole at the center of our galaxy has a gas cloud in its gravitational clutches – but the gas cloud isn’t giving up without a fight If gas clouds could think, this one would class itself as the luckiest bunch of atoms in the universe. The front portion…

Supermassive black hole’s high spin rate provides a direct clue as to how it grew

For the first time, scientists have measured the spin of a supermassive black hole at the center of a galaxy – a measurement that could help explain how these objects got so large. Supermassive black holes are thought to occupy the center of virtually every galaxy in the universe. They…
