can you describe the differences between spiral galaxies and elliptical galaxies?
user
spiral galaxies have a flat, pinwhell-like structure made up of stars, dust, and gas, which is what gives them their name. they also possess a central bulge, which contains a greater density of stars towards the center. elliptical galaxies are much less structured, being elliptically shaped and resembling a basketball in appearance. they do not have a spiral-like structure, and do not contain a central bulge.
