Figure 13-9 RIVUXG NGC 7331: A Near-Twin of the Milky Way If we could view our Galaxy from a great distance, it would probably look like this galaxy in the constellation Pegasus. As in Figure 13-7, the far-infrared image (a) reveals the presence of dust in the galaxy’s plane, while the near-infrared image (b) shows the distribution of stars. These images of NGC 7331, which is about 50 million ly from Earth, were made with the Spitzer Space Telescope.
