Elliptical galaxy

A smooth, featureless elliptical galaxy with an oval to nearly round, slightly flattened or slightly elongated ellipsoidal outline. It has a bright, dense yellow-white to pale golden central core or concentration that fades gradually, evenly, and symmetrically outward into a diffuse soft-edged luminous halo with gentle elliptical contours. No spiral arms, bar, disk, dust lanes, clumpy star-forming regions, or other obvious internal structure are visible; the overall appearance is a uniform spheroidal stellar light distribution with only a subtle stellar grain or texture.
