Latest Results from Wilkinson Microwave Anisotropy Probe: Three-year Observations

The Wilkinson Anisotropy Probe has been mapping the full sky in five microwave bands to measure temperature and polarization anisotropy of the cosmic microwave background. We have announced the second data release on March 16, 2006, from three years of observations. In this talk I will try to summarize a bit of history of CMB, the WMAP mission, physics of CMB temperature and polarization anisotropy, cosmological implications of the three-year WMAP data, and some future prospects.
