Observations of the cosmic microwave background (CMB) temperature anisotropy and polarization are a foundation for the standard model of cosmology. Improved measurements of the CMB temperature anisotropy and polarization will significantly advance our understanding of the universe and fundamental physics. The best cosmological constraints from the CMB today come from the Planck satellite. The Atacama Cosmology Telescope (ACT) maps the CMB at an arcminute resolution over 18,000 square degrees in multiple microwave bands. I will highlight the recent cosmological results from ACT, and describe how the new ACT maps improve on the cosmological constraints beyond Planck. I will also describe a new observation program with the Simons Observatory project, and its potential to enable next generation cosmological studies with precision observations from the Atacama.
