Hubble unveils a deep sea of small and faint early galaxies

more »

Scientists have long suspected there must be a hidden population of small, faint galaxies that were responsible during the universe's early years for producing a majority of stars now present in the cosmos. At last Hubble has found them in the deepest ultraviolet-light exposures made of the early universe. This underlying population is 100 times more abundant in the universe than their more massive cousins that were detected previously.
