E0 galaxies, or elliptical galaxies, have no stellar disk and no gas or dust. They are typically spheroidal in shape and have little to no apparent structure or spiral arms. Sa, SBc, and S0 galaxies all have a stellar disk, and some may also have gas and dust present. E9 galaxies do not exist in Hubble's classification system.
