WebSpiral galaxies are disk shaped galaxies with spiral structure. Hubble classified them as Sa, Sb, Sc: There is a parallel sequence for spiral galaxies that have central bars: SBa, SBb, SBc The Milky Way is probably an Sbc or SBbc, something like this galaxy, M83. Elliptical Galaxies Elliptical galaxies are much smoother, spheroidal galaxies. WebBarred spiral galaxies have a similar sort of spiral structure to spiral galaxies, but instead of emanating from the bulge, the arms project out from the ends of a "bar" running through the bulge, like ribbons on either end of a baton. Again, SBa to SBc refer to how "tightly wound" these arms are. ctfppb
