telescopes. The team observed the X-rays generated in the innermost regions of the disk circling and feeding the black hole that powers the quasar. By measuring the radius of the disk, the astronomers were able to calculate the black hole's rotational speed, which was almost half the speed of light.
191:. This implies that the black hole must be spinning incredibly fast to allow the disk to survive at such a small radius. The measurement of the black hole's rotation is the first time astronomers have been able to directly measure the rotational speed of any black hole.
