# Long description

Figure 14 shows a wide-angle photograph of the night sky as seen from an observatory. The observatory buildings and nearby mountains can be seen silhouetted in the bottom of the image. A small patch of orange glow from a distant light source can be seen on the right. The night sky is dominated by a curved band of light that stretches across most of the sky: the Milky Way. Etched into the bright band of light are dark dust lanes, which show a variety of complex, filamentary structures.
