2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/10227We summarise recent Hubble Space Telescope results on the morphology of faint field galaxies. Our two principle results are: (1) the galaxies responsible for the faint blue excess have late-type/irregular morphology and (2) the number counts of normal galaxies, ellipticals and early-type spirals, are well fit by standard no-evolution models implying that the giant population was in place and mature by a redshift of $\ge 0.7$.To be published in Proceedings of IAU symposium 171, "New light on Galaxy Evolution", Eds.: R.Bender and R.
