Astronomy Encyclopedia
Publisher: Oxford | (June 15, 2002) | ISBN-10: 0195218337 | PDF | 465 pages | 31.52 MB
This book is state of the art in information. It can answer any possible question you can ask about astronomy. It is a thick heavy hard covered book. I spent two hours just reading the captions of over 500 pictures and learned things I never thought about. Get it.
