elliptical galaxies are spheroidal concentrations of billions of stars that resemble globular clusters on a grand scale. they have very little internal structure; the density of stars declines smoothly from the concentrated center to the diffuse edge, and they can have a broad range of ellipticities (or aspect ratios). they typically contain very little interstellar gas and dust, and no young stellar populations (although there are exceptions to these rules). edwin hubble referred to elliptical galaxies as early-type galaxies, because he thought that they evolved to become spiral galaxies (which he called late-type galaxies). astronomers actually now believe the opposite is the case (ie;, that spiral galaxies can turn into elliptical galaxies), but hubble's early- and late-type labels are still used.
