The differences between what can be seen in near-infrared versus mid-infrared light are dramatically displayed in these images of Sagittarius B2 from the James Webb Space Telescope. The massive star-forming region in the center of our Milky Way is home to thousands of colorful stars, which emit the near-infrared light captured by Webb’s NIRCam (Near-Infrared Camera). However, few stars emit the mid-infrared light captured by Webb’s MIRI (Mid-Infrared Instrument). In both images, the darkest area

This helps MIRI detect longer infrared wavelengths & suppress electrical currents that can mimic real light signals. go.nasa.gov/3uBXWDN | NASA Jet Propulsion Laboratory | Facebook
