Question

Quizplus · Accepted Answer

The major difference between an elliptical galaxy and a spiral galaxy is that an elliptical galaxy lacks a disk component, while a spiral galaxy has a prominent disk component. Elliptical galaxies are generally more spheroidal in shape and contain mostly old, red stars. Spiral galaxies have a flattened disk with arms of star formation and contain a mix of young and old stars. The other answer choices are not accurate or relevant distinctions between elliptical and spiral galaxies.
