The department offers an outstanding program for Astronomy Majors at Princeton University. The program is known for its excellence in research and in teaching. Our students carry out three independent research projects, in collaboration with a faculty adviser, on topics that range from planetary science to stars, galaxies, black holes, dark-matter, cosmology, the early universe, and more. The relatively small size of the department provides a warm and supportive atmosphere, informal and friendly interactions, and a flexible program plan. Our Astronomy Majors -- typically 10 to 15 students -- have access to some of the most advanced observational and computational facilities in the world for research in astronomy and astrophysics.
