A Bachelor's level degree in astronomy will not lead to too many jobs. Some planetariums or very low level jobs at an observatory. It is also possible you could get a low level entry job in some industry related to space.
Master's level and the PhD open up much greater possibilities. Planetariums, museums, college teaching, government (weather service, military, State Dept., Agriculture Dept., Commerce Dept. and possibly others), as well as industry.
Incomes vary with degree and experience, as well as where you work, but range from a low of $25K to over $100K.
Most units of University of California offer an astronomy undergraduate major, as do CalTech, Stanford, etc. Outside California major institutions offering an astronomy degree include Univ. of Texas, Univ. of Michigan, Columbia, Harvard, Yale, Ohio, and many others.
I spent 36 years of work career in astronomy (the Apollo Project, planetariums, and college teaching), and lived every day of it in New York City--not exactly the middle of nowhere. Of course, I did spend some time at Cape Canaveral for various launches, but with so many people around I never felt that was the middle of nowhere either.
