The Gaia space observatory collects unprecedented positional and radial velocity measurements of about a billion stars in our Galaxy and throughout the Local Group.
The AIP hosts the Gaia data as one of the external data centers along with the main Gaia archive maintained by ESAC.
Gaia@AIP hosts the data from Gaia data releases in a PostgreSQL database system. The data can be queried directly using the Structured Query Language SQL, so you can retrieve only the data subset you interested in. After registration, you can use the Query Form to perform your query. We also prepared a set of examples for you to get started.
