- The Institute of Astronomy offers the opportunity to study for the PhD degree, for which the normal duration of study is three years. The format is almost entirely research-based and while projects may be exclusively theoretical or observational, many combine aspects of both.
- It is normal for students to attend at least one relevant international conference during their three years of study, often presenting their own research work. Many students working on observational research projects undertake observing trip(s) to major international observatories.
