The Universe: 365 Days has been created by the founders of ´Astronomy Picture of the Day´, a website created and maintained by two astrophysicists in collaboration with NASA that has been in existence since 1995. The site has become one of the most popular on the web - it now gets one million hits a week. Using this website as a resource for The Universe: 365 Days, this book contains a visually stunning group of the best and most educational astronomy-based images available. The text that accompanies each picture is both fun and informative, engaging the reader with questions, anecdotes and the wonders of the cosmos.
