A galaxy cluster containing a structure never previously seen so far from Earth has been observed by NASA's Chandra X-ray Observatory. The cluster is also interesting to astronomers because a bright quasar, known as 3C 186, is found at its center. Dr. Aneta Siemiginowska of the Harvard-Smithsonian Center for Astrophysics led the team's research on this result and discusses it with us.
