How long does it take to become an astronomer?

It will take you 4 years to get a bachelor’s degree, 2-3 years to acquire a master’s degree, and anywhere between 4 and 6 years to obtain a Ph.D. The sooner you figure out what sort of astronomy you want to specialize in, the better.

Those with a Ph.D. can qualify for university research positions.

You can also choose to join some professional associations (the American Astronomical Society, for example).
