We present the main features of the GALEX (Galaxy Evolution Explorer) science data archive, hosted by MAST at STScI. GALEX catalogs of UV sources, images in two UV bands (near-UV and far-UV), and spectra are accessible in a VO type format. The SQL query language allows flexible browsing of the data for scientific applications. An example of scientific
application is the possibility of correlating catalogs from different archives, to build selected samples of sources and new catalogs of objects by astrophysical classes. We show one example of such application: using the matched GALEX (2 UV bands) plus SDSS (Sloan Digital Sky Survey - 5 optical bands) photometry of about 2 Million sources, by comparison with synthetic colors of astrophysical objects across all physical parameters ranges, we extract catalogs of hot stars in the MW, binaries containg WDs, low red-shift QSO candidates, and other interesting classes of objects. In some cases, the number of objects found with this technique resulted in samples orders of magnitude larger than previously available catalogs.
