I must say that I am impressed with the little magazines that come each week. About 16-20 pages of well-written, well-illustrated articles covering all sorts of things astronomical. I haven't spotted an error as yet. Up to date as well. Everyone who can read, or even look at pictures, will learn something. I've learnt stuff about the Soviet space program and the Earth's atmospheric circulation. If it was just the model, that's a hell of a lot of money for rotating and revolving balls!
