Galaxies make up all of the universe. Galaxies come in many shapes and sizes. There are types of galactic features, such as, spirals, clusters and nebulas. This is all created by solar debris and stars. This debris and nebula is the coloring of galaxies and clusters. |

All galaxies are made of stars, in which,
every star has a home galaxy. Our home galaxy is the milky way. Every
galaxy has many billions of stars, revolving around a central point,
which is thought to be a black hole. This black hole has enough
gravity to hold the whole galaxy together in a constant gravitational
pull.
When a galaxy crosses the path of another galaxy, the debris and stars of the galaxies may be misplaced. In the happenings of this, stars and nebula may switch galaxies. |

Milky Way Galaxy (our home galaxy): The milky way is a spiral galaxy which has many arms holding the billions of stars and nebulas contained within. One of the arms holds our sun along with millions of other stars. There are also many other arms surrounding the central rotation point. The Milky Way disk, the circular figure in which holds all the debris and stars, is 100,000 light years across.

Andromeda Galaxy (our galactic neighbor): The Andromeda galaxy is very
close to the structure of the milky way, meaning it is a spiral system,
with many protruding arms, that rotate around a mid point, holding all
the stars. It is also very similar in size, along with the colored
debris throughout the galaxy.
