<p>I wanted to get the OP to clear up his/her thinking. Especially since “engineering” is so broad (computer engineers and chemical engineers have pretty much zero overlap). I don’t believe that “I don’t like the sound of being an engineer, but astronomy seems cool!” is really a good way to decide on majors. </p>
<p>With math and CS, it’s more that pure math is all about doing proofs, while CS is more like an applied math. That’s why while you can find CS majors who would hate being a math major, it’s much harder to find math majors who can not at least put up with studying CS.</p>
<p>With astronomy and the engineering disciplines, there are no proofs (and most of the engineering disciplines are pretty heavy on theory; you need to know a lot of basic science for pretty much all of them). Plus, astronomy is kind of an applied science (granted, most chemistry and biology are as well), so it’s frankly hard for me to picture a mindset that enjoys astronomy but can’t get some pleasure out of some engineering major. </p>
