We maintain internationally recognized research programs that address fundamental questions on all scales from our solar system to the entire universe. Our observations cover the entire electromagnetic spectrum from radio waves to gamma rays, and we make use of telescopes all over the world as well as space telescopes and space missions. Our theoretical work makes use of state-of-the-art computational resources. Both our graduate and undergraduate curricula are continuously revised and updated, and we receive high student evaluations in our introductory courses and courses for majors. Our Observatory Open Houses have been enjoyed by the public for over 40 years. We are proud of our achievements in all of these areas, and we invite you to learn more about our department by browsing through our website!
