Suggestions for the source of the ultraviolet flux in elliptical galaxies and spiral bulges include young stars, post-asymptotic-giant-branch (PAGB) stars, hot-horizontal-branch stars, and accreting white dwarfs. Each candidate has different implications for the spectral evolution of galaxies. We review current understanding of the origin of the far-UV flux, with emphasis on recent results from the Hopkins Ultraviolet Telescope (HUT), flown on the Astro-1 space-shuttle mission in December 1990.
