Gamma rays from the narrow-line Seyfert 1 galaxy PMN J0948+0022 (center) show that its central black hole drives a fast-moving particle beam. The object lies 5.5 billion light-years away in the constellation Sextans. Brighter colors indicate higher numbers of gamma rays at energies above 200 million electron volts. For comparison, the energy of visible light is between two and three electron volts. Credit: NASA/DOE/Fermi LAT Collaboration
