What distinguishes a quasar's luminosity from a supernova's luminosity in terms of persistence?
Answer
Quasars maintain their high luminosity continuously, unlike the brief flash of a supernova
Quasars generate tremendous luminosity continuously powered by accretion, whereas supernovae are brief, catastrophic explosions.
