An intense radio source is found to coincide with a starlike object whose spectrum contains a pattern of intense emission lines in the visible range that matches that of the Lyman UV hydrogen spectral lines but is very redshifted. What is this object?

Question

Quizplus · Accepted Answer

This object is a quasar, which is a very luminous and distant active galactic nucleus with a supermassive black hole at its center. The intense emission lines and significant redshift indicate that the object is both highly energetic and moving away from us at a high speed, which are characteristics of quasars.
