Question

What give galaxies their different shapes?

Answer 1

Galaxies have many different shapes and are usually smaller and less common than other types of galaxies. A spiral Galaxy abot 2.2 million light years away. Its a Cluster, containing the Andromeda and Milky Way.

elliptical galaxies are round or oval, with stars distributed fairly uniformly throughout. They have a bulge and halo, like spiral galaxies, but don't have the flat disk of stars. The stars in ellipticals tend to be older. Irregular galaxies have no identifiable shape or structure to them
