Quizplus · Accepted Answer

The 3-dimensional shape of elliptical galaxies and spiral bulges is set by the average velocities of the stars along each of the three axes. Spiral galaxies have a flatter disk-like shape, while quasars are not shaped by the velocities of stars, but rather by the activity of the supermassive black hole at their center.
