Elliptical galaxies are more likely to be found in clusters than are spiral galaxies.

Question

Quizplus · Accepted Answer

Elliptical galaxies are generally older and formed earlier in the history of the universe, and they are more likely to be found in clusters of galaxies where gravitational interactions have caused them to merge and form larger elliptical galaxies. Spiral galaxies, on the other hand, are most often found in less dense regions of the universe and are less likely to be members of galaxy clusters.
