Chandra’s image of this nearby active galaxy revealed two large arcs of multimillion degree Celsius gas in the outskirts of the galaxy. A composite image of the X-ray (blue), the radio (pink and green), and the optical (orange and yellow) presents a stunning tableau of a galaxy in turmoil. The arcs of hot, X-ray emitting gas appear to be part of a projected ring 25,000 light years in diameter. The size and location of the ring indicate that it may have been produced in a titanic explosion that occurred in the nucleus of the galaxy about ten million years ago.
