Question
2 reasons y elliptical galaxies are considered to be older & more evolved than spiral galaxies.
Are they considered to be older because they have little instellar matter and because they rarely form new stars like the other galaxies do. They seem to be more evolved than the spiral galaxies because?
A little help on this would be appreicated, thanks
