Ringed Galaxy NGC 7020
The southern galaxy NGC 7020 presents an unusual morphology: it includes a very regular outer ring which is completely detached and which envelops an inner ring/lens zone with a hexagon surrounding an X shape.

The outer ring has a high contrast compared to those usually observed in barred galaxies, yet NGC 7020 is not obviously barred. (Description: Ronald, Buta, (November 1990). "The ringed X-galaxy NGC 7020")
