In this typically unconventional guide to the wonders of astronomy, Patrick Moore takes the reader on a journey of exploration and investigation, to the edge of the universe and back. From accounts of man's earliest star-gazing to the extraordinary nitrogen geysers on one of Neptune's moons, he offers glimpses of the almost unimaginable variety of the known universe. No dry scientific study, the book is written with all the author's enthusiasm and love for his subject and, without being condescending, aims to make even the most difficult concepts easy to understand.
