Radiação cósmica de fundo: mais informações sobre a esta radiação que teve sua origem no big bang
Brightness Ln versus frequency n of the Cosmic background radiation. The spectrum is very close to a perfect black-body, and has a temperature of circa 2.73 Kelvin. Data points from the COBE FIRAS experiment match the theoretical curve so closely that the differences do not show up at this scale. Source: http://aether.lbl.gov/www/projects/cobe/CMB_intensity.gif
