Abstract
The primary goal of the WMAP mission is to produce a high-fidelity all-sky polarization-sensitive map of the CMB radiation to determine the cosmology of our Universe. WMAP has produced a full sky map of the microwave sky in 5 frequencies, with a resolution a factor 30 higher than the previous full sky map as produced by the COBE satellite in 1992. This is the cleanest picture of the early Universe; the structures on the CMB the pattern of hot and cold spots carry information about the composition, geometry, age, etc. of our Universe. We will review the implications for cosmology of WMAP data. The highlight is that cosmology now has a standard cosmological model. With only 6 parameters the model fits not only WMAP data remarkably well, but also a host of other astronomical observations.
