My names Austin, you guys have probably seen a question from me before, And i was just sharing my information: I love astronomy and i'm trying to get as interested as i can in it. I really want to study AP science and math in my later high school years and get a job in the fields of astronomy one day. Univeristy level, like an astrophysicist. But the main reason for this question was i wanted to Email some famous astronomers or Big companys like NASA. I would like to e-mail them about my studys and ask them many questions but will you guys know if they will email me back with some information?
