This zoom in on an approximately 10°×10° region of the Planck First Light Survey where the Milky Way is not the predominant signal shows clearly the features which are of most interest to Planck, i.e. the Cosmic Microwave Background (CMB).
The image shows observations by LFI at 70 GHz. This is one of the frequencies at which the dominant emission is the CMB.
A related image shows the emission observed by HFI at 100 GHz.
