Mergers between equally massive galaxies usually produce elliptical galaxies.

Question

Quizplus · Accepted Answer

When two galaxies of roughly equal mass merge, the intense gravitational interactions and resulting disturbances in their structures tend to disrupt their original shapes, leading to the formation of an elliptical galaxy. This process involves the mixing and randomization of the stars' orbits, which contributes to the elliptical galaxy's characteristic shape.
