  1. 'The astronomers speculate that quasars were ignited as blackholes grew by swallowing large quantities of cold, dense gas.'
  2. 'I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes.'
  3. 'From here he suggested that in seeing quasars created from the center of galaxies, we are actually looking back in time 6000 years and watching creation as it happens.'
  4. 'At those rates, each galaxy could easily have formed the quasar and its black hole power source in just a few hundred million years.'

  10. 'Here, you'll find everything from black holes to quasars and moon rockets to space stations.'
