The HUDF has revealed high rates of [[star formation]] during the very early stages of [[galaxy formation]], within a billion years after the Big Bang.<ref name="Beckwith2006" /> It has also enabled improved characterization of the distribution of galaxies, their numbers, sizes and luminosities at different epochs, aiding investigation into the evolution of galaxies.<ref name="Beckwith2006" /> Galaxies at high redshifts have been confirmed to be smaller and less symmetrical than ones at lower redshifts, illuminating the rapid evolution of galaxies in the first couple of billion years after the Big Bang.<ref name="Beckwith2006" />
