A protogalactic cloud with slow star formation is more likely to form a spiral galaxy than an elliptical galaxy.

Question

Quizplus · Accepted Answer

Spiral galaxies are thought to form from slowly rotating protogalactic clouds with a high angular momentum. These clouds can gradually collapse and form a disk-like structure with spiral arms. Elliptical galaxies, on the other hand, are thought to form from rapid and violent mergers of galaxies, which would disrupt any existing disk structure and lead to a more spherical shape. Therefore, a protogalactic cloud with slow star formation is more likely to form a spiral galaxy than an elliptical galaxy.
