Abstract (from CDS):

A 1.5 Mpc radio galaxy has been discovered at a redshift 0.206. Using maps at three frequencies we estimate a source age ∼7.5x107yrs, an expansion speed ∼0.03c, a jet power ∼1044erg/s and an external density ≤10–6cm–3. We conclude that the source has a large size because it has expanded in a low-density ambient medium and not because it is very old.
