Declaring an Astrophysics Major

We provide below information for students who are interested in declaring Astrophysics as their concentration.

The Astrophysics program ranks top in the country. It provides an outstanding opportunity for students who are interested in exploring the mysteries of our Universe — from extra-solar planets, to stars, galaxies, dark matter and dark energy, black-holes, the expanding Universe, the Big-Bang and the early Universe. The relatively small size of the department provides a warm and supportive atmosphere, informal and friendly interactions, and a flexible program. Our astrophysics majors -- typically 15 to 25 students -- have access to some of the most advanced observational and computational facilities in the world for research in astronomy and astrophysics.

Due to the remote instructions this spring, all advising for sophomore sign-in will be done remotely.
