Future progress in our understanding of fundamental properties of the space and time will be related to the high precision CMB experiments, particularly the PLANCK, which was launched on 14 May 2009. The PLANCK is the third Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific Program.

The basic scientific goal of the Planck mission is to measure CMB anisotropies at all angular scales larger than 5 to 10 arcminutes over the entire sky with a precision of ~2 parts per million. The PLANCK mission  would be able to detect the anisotropy and, especially, the so called B-mode of polarization of the CMB sky, with unprecedented angular resolution and pixel sensitivity. Detection of this specific sort of the CMB polarization give us an opportunity to investigate the cosmological gravitational waves, which are essential part of the matter created during the inflation.

In order to achieve the main goal of the PLANCK mission many fundamental and practical investigations needs to be done. The principal objective of the DISCOVERY CMB team is to reap the maximum scientific harvest from the Danish participation in the ESA PLANCK mission in order to obtain a strongly improved understanding of the structure and evolution of the Universe, and new forms of matter related to fundamental physical processes in the sub-atomic space.

Denmark has been one of the main contributors to the PLANCK mission and the DISCOVERY CMB team has been actively involved in tackling some of the key problems of observations itself.
