The NASA/ESA Hubble Space Telescope has imaged a set of enigmatic quasar ghosts—ethereal green objects which mark the graves of these objects that flickered to life and then faded. The eight unusual looped structures orbit their host galaxies and glow in a bright and eerie goblin-green hue. They offer new insights into the turbulent pasts of these galaxies.
