Unraveling the origins of life on Earth and determining whether life exists beyond Earth will likely be two of the most significant scientific discoveries in the 21st century. The Program in Planets and Life is an interdepartmental, multidisciplinary plan of study designed for students interested in these two questions. The goal is to provide students with an understanding of the fundamental astrophysical, chemical, biological, and geological principles and engineering challenges that will guide our search for life in extreme environments on Earth and on other planets and satellites in the solar system and among neighboring planetary systems. Research on and teaching of these topics are typically performed under the rubric of astrobiology.
The program will equip participating students with the skills they will require to assume leadership roles in discovering the origins of terrestrial and extraterrestrial life over the next decades. The cooperating departments from which the Program in Planets and Life draws faculty and other resources include Astrophysics, Chemistry, Ecology and Evolutionary Biology, Geosciences, Mechanical and Aerospace Engineering, and Operations Research and Financial Engineering, as well as the Princeton School of Public and International Affairs.
Admission to the Program
The Program in Planets and Life is open to all A.B. and B.S.E. students. Interested students would normally take AST 255/CHM 255/GEO 255 in their sophomore year.
Program of Study
The following requirements are in addition to those of a student's department of concentration. By appropriate choice of courses, a student may satisfy the program and concentration requirements as well as University distribution requirements. For the certificate, core course and cognate courses may not be taken on a Pass/D/Fail basis.
1. Students must take the core course GEO 255/AST 255/EEB 255/CHM 255. This course will qualify for departmental credit if the student submits a 25-page term paper on astrobiology, with the emphasis in that department's discipline.
2. Students must take an additional four cognate courses. Only two of the cognate courses can be in the student's department of concentration or be requirements of their majors (though exceptions can be considered on a case-by-case basis). The cognate courses must be approved by the program chairperson, and students are encouraged to discuss their choices in the early stages of their planning.
3. To qualify for the certificate, A.B. students must (i) write at least one of the junior papers on an astrobiology topic and, as part of the senior thesis, (ii) devote a chapter to an astrobiology topic—both of them subject to approval by the program director in consultation with executive committee members. Engineering students must devote one chapter of their senior independent work to an astrobiology topic—again subject to approval by the program chairperson in consultation with executive committee members. The relevant content of the student's senior thesis or senior independent work will be presented at a special Planets and Life Symposium at the end of senior year. Juniors are also encouraged to participate in this yearly Planets and Life Symposium.
Sample Cognate Courses. Courses in addition to those listed below may also be considered by the committee. To reiterate, while the list provides examples, other courses can be considered to fulfill the certificate requirements, subject to review by the Executive Committee. Note: An asterisk [*] indicates a one-time-only course.

Introduces students to astrobiology, a new field in which scientists trained in biology, chemistry, astrophysics, and geosciences combine their skills to unravel life's origins and to search for extraterrestrial life. Topics include the astrophysical prerequisites for life, the RNA world, the evolution of metabolism and photosynthesis, microbes in extreme environments, and the search for life within our solar system and in nearby solar systems. Two 90-minute lectures are required. Track A will be required to take a midterm exam during fall break. Prerequisite: one geoscience, chemistry, biology, or astronomy class or instructors' permission.
Certificate of Proficiency
Students who meet the requirements of the program and of their home department will receive a certificate of proficiency in planets and life upon graduation.
