An optical image of the galaxy M87 (HST), a radio image of same galaxy using interferometry (Very Large Array, VLA), and an image of the center section (VLBA) using a Very Long Baseline Array (Global VLBI) consisting of antennas in the US, Germany, Italy, Finland, Sweden and Spain. The jet of particles is suspected to be powered by a black hole in the center of the galaxy.
