What type of galaxy is a spiral galaxy?

• s a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. Unlike flat spiral galaxies with organization and structure, they are more three-dimensional, without much structure, and their stars are in somewhat random orbits around the center
• A galaxy that does not have the clearly definedshape and structure of typical elliptical, lenticular, or spiral galaxies. Irregular galaxies typically contain large amounts of gas and dust, and their stars are often young.
• a galaxy in which the stars and gas clouds are concentrated mainly in one or more spiral arms.
