Yes!
Many students, including non-science students, are quite understandably fascinated by astronomy. So at Level 1 we offer two ASP units which have no specific prerequisites... though they do require some basic maths, so if you are allergic to maths you may need to think carefully before selecting these units.
You are free to select either of these units on their own, or both of them.
We emphasise that ASP1022 does NOT require you to pass (or even select) ASP1010 in semester 1 - though we would always encourage you to select both units as we think they are both great!
If you do wish to continue with studies in Astrophysics, these units still offer a significant contribution to your studies. ASP1010 provides a solid foundation for studying ASP2011 in second year (even though it is not a prerequisite) and ASP1022 has some content that is not specifically covered in any other ASP unit. However, a minor or major in Astrophysics does require some physics and maths units - see the advice above.
