Coincidentally, I am taking an intro-level Astronomy class this semester at my university.
So far, I'd say it has been the most interesting and enlightening science class that I have ever taken.
It is a shame that Astronomy gets overlooked in most school curricula.
I have always wondered if the reasoning behind that is because so much of its subject matter contradicts the Christian view of the world and its origins. Too, there is the fact that studying Astronomy can really put things into perspective as far as the Earth and the human race are concerned:
Man is a little germ that lives on an unimportant rock ball, which revolves around an insignificant star on the outer edges of one of the smaller galaxies.
