The sky as seen by Planck

The sky as seen by Planck

Date: 17 July 2018
Satellite: Planck
Depicts: Cosmic Microwave Background
Copyright: ESA/Planck Collaboration

Sequence of all-sky views obtained by ESA's Planck mission at increasing frequencies, from 30 to 857 GHz. For each frequency, the animation shows the map of temperature fluctuations in the cosmic microwave background, or CMB, and three measures of the CMB polarisation. In the case of the two highest frequency channels (545 and 857 GHz), which were not sensitive to polarization, only the CMB temperature fluctuations are shown.

These images are based on data from the Planck Legacy release, the mission’s final data release, published in July 2018.
