Abstract
THE radio source 3C273 has recently been identified with a star-like, superluminous object of thirteenth apparent magnitude1,2. Doppler shift measurements of identifiable line features indicate a strong red shift corresponding to radial velocity of 4 × 109 cm/sec, while the observed spectral characteristics of the continuum suggests synchrotron radiation as the dominant emission mechanism3.
