In the master programme Astronomy the compulsory modules cosmology and extragalactic astronomy, stars and planets, Milky Way and interstellar medium, methods and instruments of astronomy, classical astronomy as well as celestial mechanics and history of astronomy are offered. Two of these modules can be studied in a more intensive way as astronomical elective groups of modules. This serves to prepare students for the master thesis and to set the focus for this thesis. The first compulsory module can either be Astrophysics II or Astronomical Instruments II, as the second compulsory module students can choose either a practical training in observation-oriented astronomy or a practical training in numerical astronomy. Eventually students can choose elective modules from natural sciences subjects such as biology, chemistry, earth sciences, mathematics or physics. To complete the master programme in Astronomy an independent scientific paper dealing with a current research topic is to be written.
