How long must one be in college to get a career in astrophysics?

is it true that most astrophysics jobs require a PhD? if so, how long, in years will i have to be in college?|||There aren't many jobs in the field if you don't have a PhD in astronomy or physics (preferably physics). A PhD in physics takes 10.5 years of college on average; 4 for the bachelors, another 2-3 for the masters, and another 2-6 for the PhD after that. The job market is pretty bad even if you do have a PhD; many people will spend those 8-12 years in college training for a job that won't exist when they graduate, and it doesn't pay very well considering how long you spend in school. But a PhD in physics can pay very well in industry jobs, so it's useful to have one just in case you don't make it in astronomy.
