Planck reveals the magnetic fingerprint of our Galaxy

The Milky Way's magnetic field is revealed in a new map released by the European Space Agency (ESA)'s Planck mission. This image was obtained from the first all-sky observations of 'polarized' light emitted by interstellar dust in our Galaxy. Numerous researchers and engineers at the CNRS, CEA, CNES and various Universities are taking part in the Planck mission, which continues to provide a wealth of data. Four papers recently submitted to the journal Astronomy & Astrophysics analyze these results.
