Quasar jets are particle accelerators thousands of light-years long

An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma. This discovery shakes up current scenarios for the behaviour of such plasma jets.
