The silent, introverted Milky Way monster will not spin



A beast is hiding in the center of the Milky Way and it is barely moving.

This supermassive black hole, Sagittarius A * (SgrA *), has a mass 4.15 million times that of our sun. It was first revealed to scientists as a mysterious source of radio waves from the center of the galaxy in 1931; but it wasn’t until 2002 that researchers confirmed that radio waves came from something as massive and compact as a black hole – a feat that brought them 2020. Nobel Prize in Physics. Just days before the team learned about their Nobel on October 6, another group learned something new about the black hole: It spins slower than a supermassive black hole, moving less than (probably far less) than 1

0% by the speed of light.
