False-colour optical CCD image of the peculiar spiral galaxy NGC 4319 and the quasar Markarian 205 (small circular object,bottom). The quasar appears to be connected to the galaxy by a faint bridge of material. In the 1970s,Markarian 205 was considered "the fulcrum of the redshift controversy" - the debate about whether quasars were really extremely distant objects receding at enormous velocities relative to Earth. Observ- ations in the early 1980s confirmed that Markarian 205 is indeed very distant,whereas NGC 4319 is an unrelated galaxy in the line of sight | |
