The Cosmic Microwave Background Radiation at 50
Fifty years ago two radio engineers Arno Penzias and Robert Wilson serendipitously discovered the cosmic microwave background radiation. I will discuss the early attempts to determine its spectrum and briefly present results of the three subsequent satellite missions: COBE, WMAP and Planck. I will also present recent attempts to measure the level of polarization of the CMB radiation and restrictions that they impose on the models of very early evolution of the universe.
