The "fast" jet emerging from a giant elliptical galaxy M87 (in Virgo). At the extreme left of the image, the nucleus of M87 consisting of an accretion disc around a supermassive black hole is seen as a bright spot. The electron-positron jet may be accelerated by the BH electromagnetic "Blandford-Znajek" mechanism. The synchrotron radiation is produced by high-energy electrons that spiral in the magnetic field. Jets are visible in the radio, optical, X- and gamma-rays. Credit: NASA, on-line at http://science.nasa.gov/newhome/headlines/images/agn/m87_jet.jpg
