The cluster of galaxies Abell 194 has within it the strong radio source PKS 0123-016. Spectroscopic and photometric data obtained in the field of this source have been combined with VLA maps to reveal a remarkable example of a jet/cloud interaction at the site of the peculiar galaxy known as Minkowski's (1958) object, which lies in the path of one of the radio jets discovered in this region. Optical results obtained can be used to rule out shock heating and power-law photoionization for this source and indicate a stellar origin for the ionizing flux. It is suggested that Minkowski's object was produced by a burst of star formation triggered by the impact of the jet on an obstructing cloud in its path.
