The Milky Way galaxy is epic! Wait, what is the Milky Way galaxy?  It sounds delicious!
Hmm...it's a barred spiral galaxy...and it has a bunch of hard-to-pronounce arms...but definitely no milk (or chocolate or caramel.  Booo.)  It's not called the Milky Way because it has some delicious ingredients.  It's called that because it's looks hazy and milky from Earth.
Now for those ridiculously named arms:
The arms are named after the constellations that are seen in those directions.  Ummm, by the way, a constellation is a group of stars that form patterns.  Just so you know.
Let's see . . . the major arms are Cygnus, Perseus, Sagittarius, and Centaurus.
Our solar system is in a minor arm called the Orion spur.  I hate being in a minor arm.  Why not a major arm, huh?
Our arm is almost on the tip, so we can see outside of the Milky Way.
The Milky Way galaxy has a black hole in the center.  It contains gas, dust, and dark matter.
Here is a far out picture (get it?  "Far-out!" Far out, like way out there?  Never mind.)
