<p>Oh yeah, what @happymomof1 said. If you really want to do what you want free of your parents, become either a National Merit Scholar (via the PSAT) or have a GPA and test scores that qualify you for a full-ride somewhere.</p>
<p>In fact, if you had said “my parents are forcing me to be an engineer, but I really want to do creative writing!”, that’s what I would have advised. Astronomy and some engineering disciplines are similar enough, though, that it’s hard to imagine someone who really likes one but hates the other.</p>
