SPHEREx mapping of diffuse PAH and H II emission in the Galactic plane: #SPHEREx space telescope has been conducting an all-sky near-infrared spectral survey from 0.75 to 5.0 microns. We produce a large-scale map of the 3.3-micron #PAH emission feature, which is bright and detectable throughout the Galactic plane, and find a strong correlation with the thermal dust radiance measured by Planck." (The image shows the #OrionNebula in special false colors explained in the ALT text.)
