I will review some of the key science results from the 2015 Planck data release of last week. One of the exciting results of 2014 was the BICEP2 detection of B-mode anisotropies. I will review the new joint analysis of BICEP2 /Keck Array/Planck data that quanties the level of polarized dust emission in the BICEP2 field. At present, there is no convincing evidence of gravitational waves from inflation. The Planck 2015 results are consistent with simple single-field models of inflation, with purely adiabatic perturbations and low tensor-to-scalar ratio of r
