Scientific Corrections & Data Update Policy
When new space mission data releases (such as Gaia DR4, DESI, or JWST spectroscopy) refine published measurements, or when an error is identified, we update our structured records transparently.
How to Report an Issue or New Measurement
If you spot a typographical error, unit discrepancy, broken link, or newly published survey measurement that supersedes a value on FastCosmos, please reach out via our Contact page with the page URL and peer-reviewed reference or archive identifier.
Review Cadence
Each article displays its last reviewed date in the metadata bar below the headline and in its machine-readable JSON-LD metadata. Major survey updates (Gaia, JWST, DESI, LIGO-Virgo-KAGRA, Vera C. Rubin Observatory) are integrated into the shared entity and source registry and verified across the full test suite before deployment.
