The Carnegie Astrophysics Summer Student Internship Program (CASSI) is a 10 week, paid internship and educational program based at Carnegie Observatories in Pasadena. We welcome a diverse cohort of 10-15 undergraduates from colleges and universities in Southern California to join Carnegie astronomers in collaborative original research projects. CASSI interns also participate in an educational program that includes over 60 activities during the summer designed to improve students' fluency and ease with scientific communication and scientific computing. The program also features structured mentoring and other forms of professional development intended to fully support the students during the program and in their future careers. To learn more about the program or our former interns, please follow the links below or contact the program director, Dr. Gwen Rudie

Apply to CASSI 2022


The dates for the 2022 CASSI program will be

June 13 - August 19, 2022.


Carnegie is seeking undergraduate students interested in scientific research projects. We invite applications from all students in Southern California. One of the goals of the summer program at Carnegie is to increase participation and retention of under-represented groups in astronomy. We encourage Black, Hispanic, and Indigenous scholars, first-generation college students, and women to apply. Applications are due January 31, 2022.  

Students will work for 10 weeks in the summer with scientists at Carnegie Observatories on projects spanning the field of astronomy. Using data taken from Carnegie's telescopes in Chile, students will have the chance to work with senior researchers on topics such as exoplanets, the first galaxies in the Universe, accreting black holes, dark matter, and the life and death of stars. Interested students can also work with Carnegie scientists and engineers on the next generation of cameras and spectrographs for our telescopes. Upon successful completion of the program, all students will also be given the opportunity to attend the American Astronomical Society meeting the following January to present their research. In addition to research, CASSI Interns will participate in a coding bootcamp during the first week of the program as well as an educational program designed to teach crucial scientific communication skills.

Here is a map of our buildings with room numbers. It is a bit out of date (some rooms have been split and the basement of the Hunt building has been reorganized a bit). Below is a complete map of our campus.
