Abstract
The Galaxy Evolution Explorer (GALEX) was successfully launched on April 28, 2003. Over the last 7 years, the GALEX mission has expanded our understanding of the process of star formation and galaxy evolution. GALEX data, consisting of far-UV (1344-1786A) and near-UV (1771-2831A) imaging over most of the sky, and grism spectroscopy, are available to the entire astronomical community and to the general public via the Multi-mission Archive at Space Telescope (MAST). The main characteristics and access tools to the large data archive (16TB) are presented. Groups within the GALEX Science Team, and the MAST archive teams, have undertaken complementary projects to conduct all-sky searches for time-variable and transient sources within GALEX data (e.g. Welsh et al. in Astron. J. 130:823, 2005; Wheatley et al. in Astron. J. 136:259, 2008). Results and tools for variability searches developed by MAST during this process, will be made available to the general community.
