| Planck as well as balloon and ground based experiments are measuring the polarization of the sky at sub-mm and mm wavelengths with unprecedented sensitivity. The data analysis involves research in cosmology and Galactic astrophysics, which might lead to a major discovery for fundamental physics. The main goal is to characterise anisotropies in polarization of the Cosmic Microwave Background (CMB) with sufficient precision and confidence to detect the expected signature from primordial gravitational waves. At the same time, we are getting the data needed to characterise interstellar magnetic fields and their coupling with matter and turbulence in the diffuse interstellar medium and molecular clouds. I will introduce these two research fields that have become interconnected, present current results and future perspectives. |
