Using images taken over a 13-year span by NASA's Hubble Space Telescope, astronomers have assembled time-lapse video of a 5,000-light-year-long jet of superheated gas being ejected from a black hole at the center of a galaxy named M87. The sequence suggests that the escaping plasma is following a spiral- or helix-shaped magnetic field being produced by the spinning accretion disk of material around a black hole.
