If you’re new to the International Astronomy and Astrophysics Olympiad, take a look at the syllabus to see the covered topics!
Some other resources we recommend are:
- An Introduction to Modern Astrophysics by Bradley Carroll and Dale Ostlie
- Fundamental Astronomy by Karttunen et. al.
- abebooks.com sells used textbooks at a low price and in great condition.
- edX, Coursera, and other online educational platforms often have astronomy or astrophysics related courses.
- Stellarium is one of many resources (but probably the best) for studying constellations and Deep Sky Objects.
If you’ve done all of the above, and you would like to study the subject in more depth, we recommend the following books with problems:
