Key Summary
With general information webinars on 29 January and programme-specific webinars from 2 to 12 February, these events are the ideal opportunities to ask our dedicated staff, professors and students all the questions you have in mind.

Taking advantage of generations of terrestrial and space-based instruments, the Master of Astronomy and Astrophysics trains students to study the origin, structure, and evolution of planets, stars, star systems, and the universe itself.
About the Programme
The Master of Science in Astronomy and Astrophysics is a two-year programme consisting of 120 ECTS credits.
- First year: theoretical courses provide a solid foundation for further study, while you develop your research skills by undertaking a research project
- Second year: you work on your master's thesis, as front-line research is typically conducted within one of the research groups. Attention is devoted to the analysis and astrophysical interpretation of data and models, as well as to technological aspects of international astronomical research.
Astronomical research and education have a distinct international and multidisciplinary character. The emphasis is on developing and applying research methodologies to collect, analyze, and interpret astronomical observations in the context of astrophysics. Technological as well as computational and theoretical aspects are extensively covered. Thanks to new generations of instruments on the Earth's surface and in space, you can adequately study the origin, structure, and evolution of planets, stars, galaxies, and the universe. Astronomy therefore retains a central place in international fundamental research.
Upon successful completion of this program, you will have acquired:
- A thorough insight into various aspects of astronomy
- A developed understanding of the various sciences contributing to astronomy
- A critical research attitude
- The ability to define and formulate strategies to study complex questions
- The ability to integrate technological developments into basic research
- The ability to construct simple numeric and physical-mathematical models to study data within a theoretical framework
Program Strengths
KU Leuven situates itself as a leader in astronomical research in Flanders, among other things by being the only Flemish university to offer a full master's degree in astronomy. The master's program has an international focus and attracts students from many different countries.
Thanks to an extensive network of national and international collaborations, our researchers have access to large-scale modern instruments within the framework of the European Southern Observatory (ESO) and the European Space Agency (ESA). Moreover, thanks to KU Leuven, Flanders has its own professional Mercator telescope at the La Palma International Observatory, which master students can use during their training. Large-scale numerical models in the context of projects or the master thesis can be simulated on the KU Leuven Genius supercomputer with more than 8000 cores.
You obtain a broad formation in astronomy and astrophysics with strong attention to transferable skills and personal development. The curriculum is research-oriented and the master’s thesis is always well embedded into the actual research of the research groups at the Institute of Astronomy.
