Gaia is a revolutionary instrument that has given us positions and proper motions of local stars to precisions that are frankly ridiculous. One especially exciting application of this data for the cosmologically inclined amongst us is a deeper understanding of the  substructure in the Milky Way. I'll begin by giving an overview of Gaia mission as a whole and the data products it has produced. Then, I will do a bit of a deep-dive on what Gaia can tell us about dwarf galaxies and globular clusters, and what THAT can tell us about physics, if anything.
