Milky Way
The galaxy we live in is called the Milky Way. Because we live inside it, it is hard to see its shape. From Earth, we see a faint, white band stretching across the night sky. The name comes from the Latin words meaning "milky path". Looking closely at this band, we see that it is made up of billions of stars. A lot of the light coming from those stars is blocked by gas and dust in the galaxy.

Galaxy Classification
By looking at galaxies closely you can start to see similar features. Sorting schemes have been created to separate galaxies into groups based on how they look. The most famous of these was made by Edwin Hubble in 1936. It is often known as the Hubble tuning-fork because of the shape of it.
Barred Spiral Galaxy
A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure made of stars.
