Overview

• SPHEREx now delivers processed all-sky infrared data to the NASA/IPAC Infrared Science Archive on a weekly schedule, with new observations appearing within 60 days of collection.
• The telescope surveys every point of the sky in 102 infrared bands—more than any previous all-sky mission—to identify frozen water and organic molecules in the Milky Way.
• All data products and processing procedures are published alongside survey releases, ensuring transparency and enabling independent verification and research.
• Over its two-year prime mission, SPHEREx will map the sky twice annually to compile four comprehensive infrared atlases that inform studies of cosmic inflation and galaxy light history.
• SPHEREx outputs will guide follow-up observations by the James Webb Space Telescope, TESS, ESA’s Euclid and NASA’s Nancy Grace Roman Space Telescope to deepen insights into the universe.
