Redshift seen by astronomers

WebRedshifts: The Key to Quasars The answer came when astronomers obtained visible-light spectra of two of those faint “blue stars” that were strong sources of radio waves ( Figure 27.2 ). Spectra of these radio “stars” only deepened the mystery: they had emission lines, but astronomers at first could not identify them with any known substance.
