NGC 3318

NGC3318 is a barred spiral galaxy in the constellation of Vela. Its velocity with respect to the cosmic microwave background is, which corresponds to a Hubble distance of. However, 20 non-redshift measurements give a much closer mean distance of. It was discovered by British astronomer John Herschel on 2 March 1835.
NGC 3318 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
