The field has about thirty graduate students, a comparable number of research associates and visiting scientists, and twenty-eight faculty members. Graduate study and research are focused on several broad areas, including theoretical astrophysics, radio and radar astronomy, infrared and optical astronomy, and planetary sciences. Various subject areas are good preparation for study in the graduate Field of Astronomy and Space Sciences- for example, astronomy, physics, mathematics, chemistry, geology, engineering physics, and electrical and aeronautical engineering. In general, a strong background in the physical sciences and mathematics is required. Specific training in astronomy is not a prerequisite.
Most students spend their first two years attending graduate courses.
They are also strongly encouraged to become involved in one or more small research programs during that period. The programs are intended to introduce the students to research techniques and to aid them in their choice of a thesis topic. During the second year of study, each graduate student selects a research area for the doctoral thesis. Graduate students who are engaged in research interact and collaborate closely with faculty members. Graduate research in astronomy and space sciences is usually sponsored through Cornell's Center for Radiophysics and Space Research and the National Astronomy and Ionosphere Center.
