MAST hosts a copy of the Gaia DR3 catalog. The Gaia DR3 catalogue builds upon the Early Data Release 3 (released on 3 December 2020) and combines, for the same stretch of time and the same set of observations, these already-published data products with numerous new data products such as extended objects and non-single stars. The Table Access Protocol (TAP) lets you execute queries against our database tables, and inspect various metadata. Upload is not currently supported.
