This multi-colour all-sky image of the microwave sky has been synthesized using data spanning the full frequency range of Planck, which covers the electromagnetic spectrum from 30 to 857 GHz.

The grainy structure of the CMB, with its tiny temperature fluctuations reflecting the primordial density variations from which the cosmic web originated, is clearly visible in the high-latitude regions of the map, where the foreground contribution is not predominant - this is highlighted in the top inset, from the 'first light' survey.See: http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=47343
