With deep GALEX and Spitzer observations of 1000 galaxies spectroscopically observed by SDSS we can measure both the obscured and unobscured star formation In these galaxies. We present an empirical relation between various measures of star formation history (including a measure based on 8 micron PAH emission), broadband color, and dust attenuation (as measured by the infrared to UV ratio). This relation can be used to infer the attenuation in high redshift galaxies. We explore the implications of this relation for the star formation history of galaxies by comparison with models of galaxy spectra and dust attenuation. Finally, we will present the average 1300 angstrom through 70 micron spectral energy distributions as a function of stellar mass, star formation history, and attenuation.
