Astronomers of the Herschel Multi-tiered Extragalactic Survey (HerMES) project announce in the journal Nature the discovery of an unusually
massive, maximum-starburst galaxy at a redshift of 6.34, or when the Universe was only 880 million years old. Because current theories of
galaxy formation and evolution
predict smaller galaxies with slower rates of star production in the early Universe, the detection of such a galaxy is challenging.
