Spiral Galaxy Planets, Hubble’s observations give us insight into how galaxies form, grow, and evolve through time.

Spiral Galaxy Planets, A galaxy is a large group of stars, gas, and dust bound together by gravity. The classification column refers to the galaxy morphological classification used by astronomers to describe galaxy structure. A spiral galaxy maintains its spiral arms due to density wave theory. Structurally, spiral galaxies consist of one or more (and typically two or more) arms that spiral away from either a central nucleus or a central bar. All the stars we see in the night sky are in our own Milky Way Galaxy.
