Explore the infrared sky through real SPHEREx spectral-image archive records. Search a position, constrain the observation period and wavelength range, and inspect archive metadata without inventing observations.

Coordinates use ICRS. WISE 0855 uses its catalogued J2000 position; Barnard’s Star is propagated from its J2000 catalog position using SIMBAD proper motion to reference epoch 2026.0. Other targets currently require manual coordinates. Choose collections explicitly. Dates and wavelengths are optional. The DR1 cube collection is a separate all-sky product.

Your real SPHEREx archive results will appear here.
*Distinct time values are estimated from returned metadata. Multiple detector images may belong to one observing epoch. A failed archive query is not the same as zero observations.

Search the archive to build a chronological sequence.
Auto Highlights samples up to 12 epochs across the complete time range. All Observations keeps every grouped epoch available. Products sharing an observation ID are grouped into one epoch; use Product to switch wavelength products.
The red cross marks the target's ICRS position at the selected observation epoch when a verified proper-motion model is available; otherwise it marks the searched coordinate. Barnard's Star uses linear proper-motion propagation from its J2000.0 catalog position (no parallax or radial-velocity correction). SPHEREx false colour visualizes infrared detector intensity; Pan-STARRS real sky colour is a separate, static stacked visible-light g/r/i survey reference. It does not change between SPHEREx epochs and cannot show epoch-to-epoch motion. It is not SPHEREx data, and coverage is not available everywhere.
Data source: NASA/IPAC Infrared Science Archive (IRSA), SPHEREx SIA2 and IBE. The viewer extracts real FITS image, variance, quality-flag, and zodiacal layers from archive cutouts. Full FITS products remain available through their archive links.
