This composite image from 2014 of quasar RX J1131-1231 uses data from NASA's Chandra X-ray Observatory, ESA's XMM-Newton and Hubble.
X-ray data from Chandra was used to measure the spin of the quasar's supermassive black hole.
X-rays emitted and distorted from a region in the accretion disk located ~3x the radius of the event horizon led to the result that space-time at the black hole's event horizon is spinning at ~50% the speed of light.
