 Here's a Spitzer infrared space telescope image of some stars in the large Magellanic Cloud Dwarf galaxy orbiting the Milky Way. Now we're morphing this into the image taken by Webb's mid-infrared instrument. The retired Spitzer telescope was one of NASA's great observatories and the first to provide high-resolution images of the near and mid-infrared universe. As you can see, Webb, with its significantly larger primary mirror and improved detectors, allows us to see the infrared sky with significantly improved clarity, enabling even more discoveries. For example, Webb's image shows the interstellar gas in unprecedented detail.
