elliptical galaxies

Elliptical galaxies are a type of galaxy characterized by their smooth, rounded, and featureless appearance, resembling spheres or elongated ellipsoids. They contain mostly older stars, with little new star formation, and have less gas and dust compared to other galaxy types. These galaxies typically lack the complex structures like spiral arms seen in spiral galaxies and often result from galaxy mergers. Elliptical galaxies can vary greatly in size, from small dwarf ellipticals to giant ellipticals, and they are common in galaxy clusters, playing a key role in the universe's large-scale structure.
