Master in Astrophysics

California Institute of Technology (Caltech) in Pasadena is internationally renowned for its focus on science and engineering and for a research environment that emphasizes discovery and innovation. Founded in 1891, Caltech combines small class sizes with world-class faculty and a culture that encourages independent inquiry. The institute’s achievements in fundamental research and technology transfer make it a top choice for students seeking an intensive STEM education and close mentorship from leading scholars.

Caltech offers a compact, high-impact academic setting where undergraduates and graduate students participate directly in cutting-edge projects across physics, biology, engineering and computation. Research opportunities are abundant and accessible, with students contributing to labs, observatories and centers that address global challenges. The collaborative, interdisciplinary approach cultivates both deep technical expertise and the ability to work across fields.

As a relatively small campus community, Caltech provides strong academic support, mentorship and networking in the greater Los Angeles research ecosystem. For international students drawn to rigorous STEM training, Caltech delivers concentrated resources, hands-on research experiences and pathways to meaningful scientific contribution in industry, academia and public service.

The Master in Astrophysics at California Institute of Technology is for students who have a Bachelor's degree and want to learn more about the universe. This 2-year Master's program is taught in English and takes place on campus in Pasadena, United States.

The curriculum covers specific subjects like stellar physics and planetary science. You will develop skills in data analysis and learn how to use programming languages like Python. Hands-on components include working with telescopes and analyzing real astronomical data.

After graduating, you can work as a Research Astronomer, Space Scientist, or Data Analyst. You can also find jobs as a Physics Teacher or a Science Writer. Top employers in this field include NASA, the European Space Agency, and universities with astronomy departments.
