Astronomers report most 'outrageously' luminous galaxies ever observed
Astronomers report that they have observed the most luminous galaxies ever seen in the Universe, objects so bright that established descriptors such as 'ultra-' and 'hyper-luminous' used to describe previously brightest known galaxies don't even come close. The lead author says, 'We've taken to calling them 'outrageously luminous' among ourselves, because there is no scientific term to apply.' Ref. Source 9t.
