This is free for anyone who wants it. It’s an interactive and very detailed program that provides a vast amount of information about the night sky at various times of day and points on earth. I’ll probably bring it into class today to show it for real if there’s time. It’s a lot of fun to play around with, but i know that not all of what we’re doing has to do with space. But even just in terms of informational purposes and images it’s a useful tool.
