How are elliptical galaxies different from spiral galaxies?

Both the Milky Way and the Andromeda Galaxy are currently spiral galaxies, but in a few billion years they will collide. The result is expected to be an elliptical galaxy combining the two: Milkdromeda? Galactic collisions in general will destroy the structure of pristine spiral disks. read more

Elliptical galaxies also have dense centers, but they do not protrude from the body of the galaxy. • Spiral galaxies are the most common type of galaxies and contain three quarters of all the galaxy population. Elliptical galaxies are relatively rare and contains only one fifth of the galaxy population. • Spiral galaxies have star forming regions in spiral arms; therefore have majority Population I stars. read more

An elliptical galaxy is 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. read more
