Cosmoglobe is an ambitious effort to build a single coherent model of the radio, microwave, and submillimeter sky through joint analysis of the best available datasets in the world, with a key sub-goal of one day perhaps discovering gravitational waves from the Big Bang. In this talk, I will outline the first major milestone of this project that was published in March this year, namely the world's first joint analysis of WMAP and Planck's Low Frequency Instrument from raw time-ordered data to a model of the microwave sky. By solving a fundamental calibration problem that eluded the WMAP team, this novel end-to-end analysis has finally yielded WMAP maps that are free from large-scale polarization systematics. The resulting maps are now for the first time consistent with Planck sky maps, and the two experiments can finally be combined to produce world-leading science. I will conclude with a look forward for Cosmoglobe, and discuss how this paradigm shift in CMB analysis can be applied for future experiments, including Simons Observatory, LiteBIRD, and CMB-S4.
