The historical confusion between the nebulae of ionized gas in the Milky Way and the external galaxies derives from the use of general catalogues, su

It was the first detection of Cygnus A, one of the brightest of all extragalactic sources (that is, located outside our Galaxy) in the radio region. These observations, made at low frequencies (160 MHz) and with the aid of small receivers, gave only

For 3C 48, optical exposures of the corresponding field indicated an object with a stellar appearance; its spectrum showed very strong emission lines that at fir

It is remarkable that 9 clearly significant lines associated with the same redshift .. = 1.9470 could be unambiguously identified. In Figure 10.1 the spectrum of another quasar, 1209+107, obtained with a photon-counting detector, is shown: in addition to the
