hi friend it is best ans by expert -
Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that appeared to be similar to stars, ratherthan extended sources similar to galaxies.Their spectra containvery broad emission lines, unlike any known from stars, hence the name"quasi-stellar." Their luminosity can be 100times greater than that of the Milky Way.Most quasars were formed approximately 12 billion years ago, and they are normally caused by collisions of galaxies, with the galaxies' central black holes merging to form either a supermassive black hole or a binary black hole system.
