The legacy data release on July 17 2018, and the associated papers, mark the end of European Space Agency Planck mission to map the cosmic microwave background. For this final data release the calibration methods were substantially revised, giving a marked improvement in the polarization maps from both the Low- and High-Frequency Instruments. I will briefly review the mission and the final cosmological results, before discussing what the Planck results tell us about polarized dust, synchrotron radiation, and anomalous microwave emission in the Galaxy. I will finish by describing how new ground-based observations are clearing up some of the significant questions left unanswered by Planck.
