Figure 18-7: R I V U X G
Gas and Dust in the Milky Way There are so many stars that they aren’t easy to see individually, resulting in the diffuse whitish band that gives the Milky Way its name. Red glowing gas clouds (emission nebulae or H II regions) can be seen in the foreground, and dark, dusty regions that block starlight are concentrated close to the midplane of the Milky Way Galaxy. This wide-angle photograph also shows the three bright stars that make up the “summer triangle” (see Figure 2-8).
