What occupations are there in the astronomy field?
To be a scientist it requires a lot of study and and commitment.
My suggestion is to avoid the career in physics and research in general if you are not very enthusiast of your field of study, because you never know where and how you will find a job.
You may need to travel around the world, change nation every couple of years and you risk that your job depends on the current political situation of grants and projects.
Once you are sure that you love astronomy and you will study it anyway, I think it is a field of research with good opportunities if you are available to move.
