An international team of astronomers has gathered new data that helps to explain the origins of quasar particle jets. These are enormous jets, hundreds of thousands of light-years long, emanating from the supermassive black holes at the heart of distant galaxies. They're mysterious because the energy of particles they emit goes down across the length of the jet. This new theory proposes that the jets are emitting particles through synchrotron radiation; where the environment close to the black hole acts as a natural particle accelerator.
