We have posted the lecture material on this website for quick access for those who need it without having to navigate cCanvas.
Hopefully we'll return to full in-person instruction and can return to a more full implementation of this open format in the near future. Until then, if you would like more info about Astro 150, please contact Prof. Steven Kawaler at Iowa State University.
The text book for this class is, believe it or not, totally free and available online! Here is a link to Open Stax: Astronomy
This is a collaborative text expanding on one of the best ``old school'' astronomy textbooks (one that I used to use) - it has been fully updated by the original authors along with a team of astronomers from across the globe (including me). It has been made possible through the Open Stax initiative.
You may access the entire text online, download it as a PDF for printing, or if you'd rather have someone else go to that trouble, you can buy a printed copy directly from the publisher. Check out the link above. The ISU Bookstore may have a few printed copies, but at a price.
Readings will be assigned in this text and in other web-based sources - see the course outline and announcements on the website.
