As I always talk about other such as galaxy, nebula, sun, and moon and other things. For today I want to talk about our own galaxy, Milky Way Galaxy. The Milky Way galaxy is most significant to humans because it is home sweet home. But when it comes down to it, our galaxy is a typical barred spiral, much like billions of other galaxies in the universe. Let's take a look at the Milky Way.

The Milky Way is a barred spiral galaxy, about 100,000 light-years across. Spiral galaxies make up about two-third of the galaxies in the universe. Unlike a regular spiral, a barred spiral contains a bar across its center region, and has two major arms. The Milky Way also contains two significant minor arms, as well as two smaller spurs. One of the spurs, known as the Orion Arm, contains the sun and the solar system. The Orion arm is located between two major arms, Perseus and Sagittarius.
