Why galaxies are of different shapes??
Answers
Galaxies have very dynamic shapes, meaning that they can change over time. For example, if a galaxy is left alone and undisturbed for a long time they become more flat, elliptical and spiral shapes whilst galaxies that have been disturbed, or rather, collided with another galaxy become more spherical and round.
Hope it helps u friend

Galaxies have very dynamic shapes , meaning that they can change over time.
If the galaxy is left alone and undisturbed for a long time they become more flat, elliptical and spiral shapes whilst galaxies that have been disturbed or rather, collided with another galaxy become more spherical and round.
All galaxies began with an elliptical shape, which is mostly a result of the centrifugal force of the spinning gas cloud.
Like pizza dough being spun into the air the gas cloud flattens to a thin disk shape.
Only the small center of the galaxy retains a spherical shape do to its slow rate of rotation and density.
