«Giant galaxies, like Andromeda and our own Milky Way, are thought to form through repeated mergers with smaller galaxies and through the accretion of vast numbers of even lower mass «clouds» — dark objects that lack stars and even are too small to call galaxies,» said David A. Thilker of the Johns Hopkins University in Baltimore, Maryland.
