Having undertaken various other courses with Open Learn this does cover quite a lot of material, so there is some cross over, which is fine to recover materials in a different context.
- The Sun is a nice 8 hour course that covers about or local star, and the processes within.
Worth checking out if you want to learn more about Astronomy and what is out there in the galaxy and beyond, however Open Learn offers more courses on other subjects too.
I have also obtained a certificate in contemporary science from the Open University, which was mostly undertaking Astronomy and Planetary science courses. So I was signed up to Open Learn anyway,
