#SPHEREx confirms predictions for artificial #SatelliteTrail pollution in #LowEarthOrbit: https://arxiv.org/abs/2605.27501 -> "SPHEREx observations obtained between May and September 2025 indicate that 73[...]% of the images already show satellite trail contamination, with an average number of N=2[...] trails per exposure, providing observational validation of the published light contamination models."

SPHEREx Widefield Infrared Spectral Mapping of Interstellar Ices and Polycyclic Aromatic Hydrocarbons: #SPHEREx Maps Vast Galactic Ice Regions: https://www.nasa.gov/missions/spherex/interstellar-glaciers-nasas-spherex-maps-vast-galactic-ice-regions/

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."
