Hey! I'm doing Science Olympiads and my category is Astronomy. We're allowed to bring in a laptop with whatever we want on it but it just can't connect to the internet. Can you recommend any software, databases, or etc that would be useful to have? Normally, the questions are basic astronomy related stuff. They'll show us a picture and ask us to identify what's being shown...or they'll ask us to use formulas. Anything will be useful. Thanks.
