[en] The image (excluding the jet) of 3C 273 has been resolved with structure extending approx.15'' from the quasar to a surface brightness level, m/sub R/roughly-equal25 mag arcsec-2. The integrated magnitude of the underlaying nebulosity, Rroughly-equal16, corresponds to M/sub R/roughly-equal-25, and the isophotal angular diameter to Droughly-equal90 kpc
