"A quasar (contraction of QUASi-stellAR radio source) is an astronomical source of electromagnetic energy, including light, which shows a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law, which implies that quasars must be very distant and hence very luminous. If that is the case, then quasars dwarf the energy output of the brightest stars. They may readily release energy in levels equal to the output of hundreds of average galaxies combined."

The word 'quasar' is a shortening of "quasi-stellar radio source". It's a star-like celestial body that sends out radio waves and other types of energy.

Quasar is short for QUASi stellAR object. It's a star gone crazy.
Read "Cosmos" by Carl Sagan if you're into quasars , pulsars , supernovae and other cosmic madness.

star that is really far away (thus was formed close to the very beginning of time), and due to cosmological redshifting, they seem to be moving away from us at about 90% of the speed of light.
