Early-type galaxies include elliptical and S0 ("lenticular") galaxies.
They are round or elliptical in outline. Elliptical galaxies typically
little gas and dust, no spiral arms or disk, and few hot, bright
stars. Lenticular galaxies are also round or elliptical in outline, but
have a disk component as well. Early-type galaxies are sometimes the
hosts of quasars and powerful radio sources. Images of those objects are
