XRISM Captures Sharpest Image Yet of Fast-Spinning Black Hole
XRISM, a joint JAXA-NASA mission, has captured the sharpest X-ray image to date of a rapidly spinning supermassive black hole in galaxy MCG–6-30-15, providing new insights into black hole spin and the environment near the event horizon by combining high-resolution data with other telescopes, and confirming the presence of material orbiting close to the speed of light.
