What stars do elliptical galaxies contain?

They contain less gas and dust, which means fewer new (and brighter) stars are born. The existing stars inside an elliptical galaxy tend to be older, giving off more red light than younger stars. If fewer elliptical galaxies have been spotted, why do astronomers think they dominate? read more

Spiral galaxies are hotbeds of star formation, but elliptical galaxies are deader. They contain less gas and dust, which means fewer new (and brighter) stars are born. The existing stars inside an elliptical galaxy tend to be older, giving off more red light than younger stars. read more

Unlike flat spiral galaxies with organization and structure, elliptical galaxies are more three-dimensional, without much structure, and their stars are in somewhat random orbits around the center. They are one of the three main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work The Realm of the Nebulae, along with spiral and lenticular galaxies. read more

Elliptical galaxies contain more gas, dust and young stars than do Sa galaxies. False Until recently, most astronomers thought elliptical galaxies were shaped like oblate spheroids. read more
