Faint Blue Galaxy Resource Page

In an article called The Evolution of the Universe, John P. Huchra and Margaret J. Geller tell us that: "There appears to be a relatively random distribution of small distant blue galaxies," and that "Each square degree of sky contains more than 300,000 blue galaxies..." 1

Another article says that "A key astronomical observation is that galaxy counts reveal a large ... density of very faint, blue, field galaxies."  And that "Despite intensive observational and theoretical work for nearly two decades, such high counts remain a major cosmological mystery..." and that "even deeper ... surveys by several groups ... did not reveal the expected, high-redshift population..."  The authors also state that "the galaxies indeed exceed their model predictions by large factors ..." They also "strongly suggest that we need to invoke an unknown, possible complex, mixture of physical processes to account for the faint blue galaxies, rather than ... a single ... mechanism ..." 2

Another article on this topic tells us that: "while confirming the existence of a blueward trend of galaxy colors at faint magnitudes, it is found that the colors of the faintest galaxies are generally not as blue as found by Tyson (1988) ..." 3

Another article says that the "Blue Galaxies are small distant galaxies, billions of light years away. We are therefore seeing them as they were when both they and the universe were ... young.  You might think that because (they) are so far away that their light would be ... strongly red ... (but since they) ... were forming new stars ... most of their light was emitted in the blue and u.v. regions of the spectrum ..." 4
