Hubble proved that some distant clouds of light in the sky are actually distant galaxies that lie well beyond the boundaries of our own home galaxy, the Milky Way.

I have read third book of Adams 101 series, and I can say readily that Astronomy 101 is the best one. Author regularly classified nearly all matters which are related to cosmos. Before to start reading, she has tried to enlighten readers about some subjects, such as units of measurement. This is helpful attempt for readers, in particular who do not know much about astronomy.
Furthermore, author has began with the Sun, and then has explained all inner and outer planets, in turn, at length. I have learned a lot of things about both the Sun and planet that is really fascinating. For example, even though the Sun looks like yellowish, it is indeed white.
Moreover, besides planets which orbit our solar system, author has mentioned about comets, meteors, asteroids, stars, and so on. I have always been wondered how stars birth and death. Thanks to this book, I am a little bit satisfied. In addition to these basic and nearly simple subjects, big bang, dark matter, dark energy and black holes also were elucidated.
However, you should not forget that it is a crash course, and this means is it contains a lot of title. That is why author describes all matters briefly.
