Surveys of the sky in two bands, far‐UV (FUV) and near‐UV (NUV), are being performed by the Galaxy Evolution Explorer (GALEX). The UV surveys and the resulting catalogs of UV sources, linked to a multi‐wavelength archive, allow us to detect and characterize with unprecedented sensitivity certain classes of astrophysical objects, including low‐redshift QSOs, hot white dwarfs (WD) in the Milky Way, and star‐forming galaxies. We characterize the nature of the UV sources detected in the major GALEX surveys, that have varying depth and coverage, and in particular we discuss the sample of GALEX‐detected hot WDs in the context of Milky Way models.
