Using new deep VLA and HST observations of the large-scale jet in 3C 273 matched to 03 resolution, we have detected excess near-ultraviolet emission () above a synchrotron cutoff spectrum accounting for the emission from radio through optical (–). This necessitates a two-component model for the emission. The radio–optical–X-ray spectral energy distributions suggest a common origin for the UV excess and the X-rays from the jet.
