In need of more movie recommendations.

Thanks for the recommendations! Deep Impact, Armageddon, Solaris, Space Cowboys, and Octobers Sky all sound great. I recall hearing that the maker of Star Trek used real astronomy in his movies, I might have to watch that again too.

Lets see. First of all, astronomy as in space? Or traveling to the space and whatnot?

I didn't make myself clear in my post, I will be judging the actual astronomy, meaning it has to take place in a real universe. Preferably the Milky Way since my class is focusing on that area.

Would October Sky count?

Possibly.

Regarding mystery: thrillers, espionage, suspense or what?

I prefer thrillers and suspense.
