Fig. 1
Image of the z = 0.89 galaxy obtained with the Hubble Space Telescope in the I band (see also Muller et al. 2006). The positions of the SW and NE images of the quasar are indicated. The distance between them is one arcsecond. Note the high extinction toward the SW image of the quasar, produced by the interstellar medium of the intervening galaxy.
