In recent years, there have been about 150 job openings for astronomers in North America, while the number of Ph.D.s conferred annually in recent years has averaged about 125. It is common for astronomers to spend from three to six years in postdoctoral positions before finding a steady position in a university department, national facility, or government lab. In such a small and popular field, only those with a quality education, ability, and passion for the subject are likely to find a permanent position. Astronomy training, however, emphasizes a remarkably broad set of problem-solving skills. With careful selection of graduate school courses and experiences, one may prepare for an interesting and productive career in a related field, such as industrial research, education, and public information.
Astronomy is interdisciplinary.
Our 'product' is knowledge about the universe, something you can't own or sell. Salaries are reasonable, but competition for jobs is stiff and the hours are very long. If you are considering a career in astronomy, you must be motivated by a love of discovery and the pursuit of knowledge. Joe Harrington, Massachusetts Institute of Technology. For these astronomers, teaching is their major activity.
