Elliptical galaxies, also known as oval-shaped galaxies, are one of the three main types of galaxies in the universe. They are characterized by their lack of structure and spiral arms, as well as their round or elliptical shape. A few synonyms for elliptical galaxies include lenticular galaxies, which are disk-like with a bulge, and spheroidal galaxies, which are nearly perfect spheres. Some other synonyms that may be used are non-star-forming galaxies, featureless galaxies, smooth galaxies, and early-type galaxies. Regardless of the term used to describe these galaxies, they are among the oldest and most massive objects in the universe, offering valuable insights into the history and evolution of our cosmos.
