Description
The Planck satellite has completed the first whole sky map of dust polarization in emission. The data is revealing a new sky we have started to explore. The observations have the sensitivity and angular resolution to image dust polarization over the whole sky. For the first time, we have the data needed to characterize the structure of the Galactic magnetic field and its coupling with interstellar matter and turbulence, in the diffuse interstellar medium and molecular clouds. The data analysis also involves the characterization of the polarization properties of dust. I will present the Planck observations, and the science questions we are investigating with results from the first Galactic Planck polarization papers.
