After the instruments collect the desired data, astronomers use it to help explain how the universe works. Professionals propose hypotheses, collect more data, interpret it, and create theories. Like amateur astronomers, professional astronomers are often very passionate about their work. Perhaps some of you will become professional astronomers. Look at some of the offerings for astronomy jobs at the American Astronomical Society, Job Register.
Most amateur astronomers love to share their passion for astronomy with others.
I share my passion and devotion to stargazing every time I drive my car. With the plate on an astronomical car, you would have an auto -matic pun. Nearly every person I come into contact with, young or old, shares the same basic expression about astronomy. Once they discover I am a stargazer, their eyes express interest. Indeed, sometimes their eyes actually begin to sparkle and a great big, happy grin consumes their face.
