This map shows the distribution of compact sources across the sky, as seen by Planck. Shown here is just a selection of the tens of thousands of compact sources included in the Second Planck Catalogue of Compact Sources. The catalogue includes data from the full Planck mission, surveying the entire sky in nine different wavelengths spanning the far-infrared to radio, covering the spectral range 30 GHz to 857 GHz. Featured in this image are the sources found using three of Planck’s nine frequency channels: 30 GHz (shown in red), 143 GHz (shown in blue) and 857 GHz (shown in green).
