The Atacama Cosmology Telescope observed the cosmic microwave background for five years from Chile, surveying half the sky at high angular resolution in three frequency bands. In March, the final maps and core cosmology results were made public. These include state-of-the-art constraints on parameters in the standard cosmological model, Lambda-CDM, as well as constraints on many extended cosmological models. In this pizza seminar, I will briefly review how we infer cosmology from CMB maps and discuss some of the key ACT cosmology results. I will briefly highlight some of the exciting science that is yet to come from analysis of secondary effects in the ACT maps.
