This book is like a traveler's guide to the galaxies , explains and views
the origins , evolution and collision of the galaxies , We know that a picture is worth a thousand words and that's real here in this book , few and simple texts , too much and very complex images thanks to Hubble. Man !! even Helen Keller can't understand what the galaxy actually is , without images and that's what made this book amazing .I liked Messier 82 galaxy , a cup of tea would be pleasurable there :D .
