GALEX has identified large numbers of extra galactic objects that are too faint to be observed by FUSE. These star forming systems are potential sources of Lyman continuum (Lyc) radiation and may contribute to the metagalactic background radiation that ionizes most of the baryons in the universe. By measuring the level of Lyc radiation leaking from these galaxies we can quantify the contribution of stars, relative to quasars, to the ionizing background at low redshift (0.025
