NASA's Spitzer telescope has helped researchers catch two galaxies merging, and now it's created the clearest panorama of our Milky Way galaxy. The telescope took over 2 million infrared snapshots of our galaxy over the course of a decade, and with the help of GLIMPSE mapping data, researchers were able to create a stunning 360-degree picture. Since our galaxy is shaped similarly to a flat disk, most of the stars that we see are concentrated in the middle. That's how the telescope was able to capture over half the stars in the galaxy's disk, even if it only covers 3 percent of the entire sky. NASA plans to use the panoramic map to help guide the James Webb Space Telescope into areas where stars form, to make even more detailed observations.
