The face-on spiral galaxy IC 5332, in the constellation Sculptor, is an SABc-type with weakly barred features and loosely coiled arms.IC 5332, which is located approximately 30 million light-years away in the constellation Sculptor, and has an almost face-on orientation to Earth. To explain what is meant by ‘face-on’, it is helpful to visualize a spiral galaxy as an large disc. If the galaxy is oriented so that it appears circular and disc-shaped from our perspective here on Earth, then we can say that it is ‘face-on’.
