Shifty Jim writes in with an article at space.com reporting that a cluster of galaxies harboring black holes may be the source of a massive cloud millions of light years across. Quoting: "A giant cloud of superheated gas 6 million light years wide might be formed by the collective sigh of several supermassive black holes, scientists say. The plasma cloud... might be the source of mysterious cosmic rays that permeate our universe... The plasma cloud is located about 300 million light years away near the Coma Cluster and is spread across a vast region of space thought to contain several galaxies with supermassive black holes... embedded at their centers."
