How do I become a a professional astronomer?
1 Answer
A Ph.D in Astronomy or cosmology usually takes about 4-5 years and consists of a number of course, but more importantly you must produce a "new piece of research" in the form of a thesis.
Explanation:
You will need a Ph.D if you want to be a professional astronomer. This usually involves taking a B.Sc. in physics with a major in astronomy or cosmology. You will also need a very strong background in math.
Once you finish a B.Sc. - about 4-5 years, you can then go on to do an M.Sc. in Astro/Cosmology, which usually takes another 2-3 years. This usually involves more course work and researching and writing a thesis on some astro related topic, that does not necessarily entail, "new original research".
Once you have an M.Sc, you can then consider doing a Ph.D. wherein you first need to pass a candidacy exam (which basically ensures you can complete a Ph.D.), find a thesis supervisor, select a topic and get down to research. You will take more courses, but the emphasis is not so much on courses, but working on your thesis topic. Most Ph.Ds. are completed in about 4-5 years at which time you will be close to 30 years old and can start looking for an academic position in Astro/Cosmology!
