Question

Quizplus · Accepted Answer

Elliptical galaxies are typically redder and rounder than spiral galaxies. This is because they contain older stars that have been depleted of the gas and dust necessary for new star formation, resulting in a redder color. Additionally, their shape is more rounded due to the random orbits of their stars, compared to the orderly rotation of a spiral galaxy.
