Astronomers used a powerful virtual radio telescope to observe a distant active galaxy. The observations revealed a ribbon-like jet of super-heated plasma. The plasma reaches temperatures of more than 10 trillion Kelvin, indicating that a pair of supermassive black holes are energizing the center of the galaxy.
