We present GALEX FUV, NUV observations sampling the outskirts of the Magellanic Clouds and the entire Magellanic Bridge, the nearest example of a tidal HI feature and low metallicity environment. These imaging data (covering several hundred square degrees) provide a unique census of hot stars (young or evolved) in the region, and permit a resolved study of star formation in conditions quite different from the Milky Way. At present, only the periphery of the LMC and SMC can be observed due to brightness safety limits. By matching our GALEX source list to optical-NIR stellar catalogs, we accurately classify detections according to their observed spectral energy distribution. The distribution of young, massive stars is compared to the gas surface density within extensive Magellanic System HI structures, probing the Schmidt Law at spatial scales approaching 200 pc. Although the exposure level of our GALEX data varies within the survey area, the deepest available imaging allows us to accurately photometer sources an order of magnitude fainter than the brightest known PNe in the MCs. In these regions, we are able to study a relevant portion of the hot evolved stellar population and test stellar evolution models at low metallicity.
