Abstract 

  Planck satellite is the European Space Agency’s survey on the cosmic microwave background radiation. It provides the most state-of-the-art measurement of the cosmological parameters and physics of the early Universe. I will give an overview of the current state-of-the-art cosmology provided by Planck satellite, which includes: cosmological parameters measurement, gravitational lensing, B-mode polarization and its relation to BICEP results, constraints on inflation etc., and discuss how will the future optical and radio astronomy experiments can sharpen the prediction of cosmology and constrain the nature of dark energy.
