The Hubble Ultra Deep Field seems to have a lot of dark areas in it. With a more powerful telescope, will we find galaxies in them?

Astronomers believe there are many more galaxies to be found within the Hubble Ultra Deep Field, a patch of sky in the constellation Fornax where the Hubble Space Telescope acquired the most penetrating views of the cosmos at visible and near-infrared wavelengths. Unfortunately, the light from more distant galaxies is so redshifted Hubble cannot detect it.
