WebBoth types of galaxy possess roughly spherical ‘halos’ of scattered stars, gases and dark matter extending beyond their visible portions. Galactic halos are clearer in spiral galaxies where the spherical halo contrasts with the shape of the flat disk. In an elliptical galaxy, distinction in shape is less defined.
