And there they've found more than just stars. Some galaxy cores rank among the most brilliant and energetic entities in the universe. Spewing out jets of radiation that extend for thousands of light-years, the cores of active galaxies can accelerate particles to energies dwarfing those of the biggest accelerator on Earth.
Powerful cores require powerful energy sources. Many astronomers now believe that compact, supermassive black holes may fuel the fireworks at the center of some ...
