The Milky Way Atlas
The Milky Way, our home Galaxy, is a large concentration of gas, dust, and a few hundred billion stars.
Our star, the Sun, is one among them. The Milky Way is called a spiral galaxy for its spiral arms, where
much of the gas is concentrated.
After an overview of the data groups, we will lead you through the Milky Way Atlas in a series of
self-guided tutorials, then provide a reference for each data group.
