The dwarf galaxy also is of interest because it provides clues to how the early simple universe became re-ionized by early star formation, moving it from the so - called cosmic Dark Ages of neutral gases to the development of the complexly structured universe now in existence, where the gas between galaxies is ionized.

While UDGs were originally identified in the cluster environment, several theoretical models suggest that UDGs are a subset of the
