The different types of galaxies
There are four main types of galaxies the we know
of so far. They are (from top to bottom then
right) the spiral like ours (the milky
way)lenticular, Elliptical,and
Irregular.

Spiral Galaxies
Spiral Galaxies are made of 2 major things. They
are that the shape is a large flat disk. The
galaxy also has many clusters of stars which form
the arms of the galaxy.
4
Lenticular Galaxies
Lenticular Galaxies are very similar to spiral
galaxies. The biggest difference is that they do
not have spirals. They do not have spirals
because their stellar formation has stopped long
ago. They mostly have type II stars.
5
Elliptical Galaxies
Elliptical galaxies are very different from the
other galaxies. They are more of a ball shape
when other galaxies are flatter and spread out
more. The galaxies are less dense then the other
galaxies. Since they look like lenticular
galaxies from the side they are usually not
called elliptical.

The Milky Way
The milky way is our home galaxy. It has four
main spirals. The galaxy has a bulge in the
center of it. The center is a cluster of a bunch
of older stars. Our solar system is in the outer
edge of one of the spirals. At some times in the
year we can see the rest of the Milky way as a
band of brighter stars .

Galaxies
Galaxies come in many different shapes and sizes.
They form many different patterns and colors.
Galaxies may even hold intelligent life.
