The Planck satellite was launched in 2009 to observe the cosmic microwave background (CMB) temperature and polarization anisotropies. Regarding temperature it was designed to be the ultimate full-sky CMB experiment: limited only by cosmic variance and astrophysical foregrounds, not by detector noise or systematic effects. Recently Planck released the first 15 months of temperature data and many accompanying papers with analyses and results. Even with just 15 months of data and the current status of the analysis, Planck has already reached or even surpassed many of its design goals. In this talk I will discuss the Planck space mission and several of its main results. In the second part of the talk I will focus in particular on the Planck non-Gaussianity results.
