Quasars Population Estimated From Mount Palomar Survey
Scientists led by Maarten Schmidt estimate 1 million to 6 million quasars in the universe, tracing their rise to light years after the Big Bang. The study ties quasar brightness to black hole energy, notes their rarity, and cites Osmer’s Chilean survey extending quasar redshift limits to 4.7 with no finds beyond 3.53.
