If you seek more information on the universe i would check out the book " The Universe in a Nutshell" by Stephen Hawkings. As far as the formation of galaxies go its an ongoing process of formation and evolution. If you want I can at a little later time dig out my books and try to find the info you seek, but if you get the book you can see for yourself. The book is really easy to read and illustrated. As far as some stars being galaxies 100 light years across, they can and are much larger than that. Here are some cool pages you may like,
