A pion in astronomy, limited careers. What do i do....?

Im in school for nursing (prereqs) but i keep second guessing my self over and over again. My pion is the universe (all areas in astronomy and areospace are interests) I read about the universe everyday,i study on my own. I sleep astronomy...BUT i do NOT want to be a professor. Is there anything i can get into at least somewhat easily and still be able to take care of my family? degree ideas are astronomy/astro,physics or aerospace engineer. Should i just pursue nursing and say screw it? Also any local jobs with those careers in indiana until i got a good job? I also thought about business administration to start somewhere in life.
