The optical spectra of the quasars presented a new mystery. Naming them didn't help determine what these objects were. Away from the plane of the Milky Way Galaxy , most radio source s were identified with otherwise normal-looking galaxies. The current best estimate is that quasar activity is episodic, with individual episodes lasting around a million years and the total quasar lifetime lasting around 10 million years. The light we see today is what the quasar looked like billions of years ago.

In this picture, one of these jets appears as a cloudy streak, measuring some light-years in length. There is a maximum rate set by the Eddington limit at which a black hole can accrete matter before the heating of the infalling gas results in so much outward pressure from radiation that the accretion stops. An apparently new kind of radio source was discovered in the early s when radio astronomers identified a very small but powerful radio object designated 3C 48 with a stellar optical image.
