Class Subjects: Galaxy types and age.

In this puzzle game, there are 9 major galaxy types, represented by a colorful shape of every one of them. If we begin to arrange them in picture order from left to right:

1. The first type of galaxy is the Elliptical galaxy. It is represented by a simple white elipse. Elliptical galaxies are the youngest ones, and it is believed every other type of galaxy is coming from them...

2. Shell galaxy. A shell galaxy is a type of elliptical galaxy where the stars in the galaxy's halo are arranged in concentric shells.

3. Lenticular galaxy. A lenticular galaxy is an intermediate form that has properties of both elliptical and spiral galaxies. These are categorized as Hubble type S0, and they possess ill-defined spiral arms with an elliptical halo of stars,

4. 2 Arms Spiral galaxy is barred spiral galaxy developing 2 arms.

5. 6 Arms Spiral galaxy is barred spiral galaxy developing 6 arms.

6. Barred spiral galaxy. A majority of spiral galaxies, including our own Milky Way galaxy, have a linear, bar-shaped band of stars that extends outward to either side of the core, then merges into the spiral arm structure.

7. Flocculent spiral galaxy is the same as the spiral galaxy but have wide blang spaces making it a little patchy.

8. Ring galaxy. A ring galaxy has a ring-like structure of stars and interstellar medium surrounding a bare core. A ring galaxy is thought to occur when a smaller galaxy passes through the core of a spiral galaxy.

9. Irregular galaxy. An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
