Abell 2597 Illustration (IMAGE) National Radio Astronomy Observatory Caption Deep in the heart of the Abell 2597 Brightest Cluster Galaxy, astronomers see a small cluster of giant gas clouds raining in on the central black hole. They were revealed by the billion light-year-long shadows they cast toward Earth. These ALMA data present the first observational evidence for predicted "chaotic, cold" accretion on a supermassive black hole. Credit Credit: NRAO/AUI/NSF; D.
