The Astronomy Department at the California Institute of Technology is part of the Division of Physics, Math, and Astronomy. The primary mission of our department is twofold: the performance of cutting-edge research in astronomy and astrophysics, including theory, observation, and experiment, as well as the education of undergraduate and graduate students and training of postdoctoral research associates who will comprise the scientists and leaders of tomorrow. We are located in the Cahill Center for Astronomy and Astrophysics on the Caltech campus.
