In 1963, astronomer Maarten Schmidt identified the first quasi-stellar object or "quasar," an extremely bright but distant object. He found the single quasar, the active nucleus of a far-away galaxy known to astronomers as 3C 273, to be 100 times more luminous than all the stars in our Milky Way combined.
