The Milky Way Galaxy

The Milky Way is a disc-shaped galaxy of stars, part of which can be seen as a glowing band of light that spans the sky on a very clear night.

The Milky Way galaxy is a spiral galaxy with a concentration of stars at its center. This gives the galaxy a central bulge from which arms of stars radiate out. We live in one of these arms.

This means that from the Southern Hemisphere of Earth, we look in toward the center of the galaxy; from the Northern Hemisphere, we look out to its edge.
