An Intriguing, Glowing Galaxy

A supermassive black hole may be responsible for the glowing appearance of galaxy 3C 305, located about 600 million light years away in the constellation Draco. Composite data from NASA’s Chandra X-ray Observatory and other telescopes suggests that the black hole may be interacting with interstellar gas and emitting X-rays. Or, bright radiation from regions near the black hole may infuse energy into the gas that makes it glow.
