Subject details

At the completion of this subject students will be able to:

  1. Appreciate the 'big questions' in galactic and extragalactic astronomy, and the current state of our knowledge on these questions
  2. Understand the concepts of galaxy formation and evolution
  3. Understand the way galaxies are classified and the approaches used to discover their properties
  4. Communicate basic principles and concepts about our and other galaxies, their properties and their constituents in a non-technical way understandable to the wider public
  5. Research an astronomy topic in depth, using dependable sources of astronomical information on the internet and refereed journal articles.
