In this job you need to travel places so that means you could end up going to some exotic country. Also in this job your salary is high and if you get a tenure position like associate professor you can't get fired unless you do something really stupid. This job offers retirement benefits if you work at a university or government agency. Positions at universities and government agencies usually have health and dental plans, other benefits would be accident and life insurance. Even better if you become an astronomer then when you take a sick day or vacation you get paid on all those days, but the only catch is that you need to be a full time astronomer.
