Horsehead Nebula (MIRI Image) | Webb

This image of the Horsehead Nebula from NASA’s James Webb Space Telescope focuses on a portion of the horse’s “mane.” It was taken with Webb’s MIRI (Mid-Infrared Instrument). Mid-infrared light captures the glow of substances like dusty silicates and soot-like molecules called polycyclic aromatic hydrocarbons. In this image, blue represents light at wavelengths of 5.6, 7.7, and 10 microns; green is 11, 12, and 15 microns; and red is 18, 21, and 25 microns. Credit: STScI.
