(PhysOrg.com) -- NASA's Chandra X-ray Observatory has observed an unusual galaxy cluster that contains a bright core of relatively cool gas surrounding a quasar called 3C 186. This is the most distant object yet observed, and could provide insight into the triggering of quasars and the growth of galaxy clusters.
