Caption

Maps of the direction of polarisation of primordial light represented by rods whose length is proportional to the intensity of the polarisation. Temperature anisotropies are shown in the background in colour. The all-sky map only shows large scales. The two square maps are successive enlargements of the regions bounded by a black contour (around the south ecliptic pole), which shows that Planck measured cosmological signals at scales much smaller than those that can be shown on an all-sky map.
