The Sculptor Galaxy (NGC 253)

Disc galaxies are galaxies which have discs, a flattened circular volume of stars. These galaxies may or may not include a central non-disc-like region (a central bulge).

Disc galaxy types include:

spiral galaxies
- barless spiral galaxies (type S, SA)
- barred spiral galaxies (type SB)
- intermediate spiral galaxies (type SAB)
lenticular galaxies (type E8, S0, SA0, SB0, SAB0)
