This image shows Planck's all-sky one-year survey with the location of the first six fields used to detect and study the Cosmic Infrared Background anisotropies superimposed.

The six fields, named N1, AG, SP, LH2, Bootes 1 and Bootes 2, respectively, are all located at a relatively high galactic latitude, where the foreground contamination due to the Milky Way's diffuse emission is less dramatic.

The angular size of the fields is 308 arc minutes on each side in the case of N1, AG and SP, 241.5 arc minutes on each side in the case of LH2, and 283.5 arc minutes on each side in the case of Bootes 1 and Bootes 2, respectively.

The frames show observations performed by Planck at 353 GHz and smoothed over an angular scale of 10 arc minutes.
