NASA's SPHEREx mission has produced the first all‑sky infrared survey mapped in 102 spectral bands, delivering a uniform, full‑sky dataset that astronomers say will help answer fundamental questions about the universe's origin and evolution and provide targets for follow‑up by other observatories.

Briefing
SPHEREx produced a full‑sky infrared map across 102 spectral bands — a uniform, legacy dataset that enables large‑scale cosmology, galaxy evolution studies and Galactic structure analyses.
The all‑sky survey complements and sharpens target selection for other NASA facilities, linking directly to the work being built around the agency's space telescope designed to map the Milky Way in 3D and detailed infrared follow‑ups from the James Webb Space Telescope.
