In 2017, over 200 million Americans witnessed the spectacular total eclipse of the Sun, and the 2024 eclipse is expected to draw even larger crowds. In anticipation of this upcoming event, this book takes us back in history over 150 years, telling the story of the nation¿s first ever eclipse chasers.Our tale follows the chaotic journeys of scientists and amateur astronomers as they trekked across the western United States to view the rare phenomenon of a total solar eclipse. The fascinating story centers on the expeditions of the 1869 total eclipse, which took place during the turbulent age of the chimerical Planet Vulcan and Civil War Reconstruction. The protagonists¿a motley crew featuring astronomical giants like Simon Newcomb and pioneering female astronomers like Maria Mitchell¿were met with unanticipated dangers, mission-threatening accidents, and eccentric characters only the West could produce. Theirs is a story of astronomical proportions. Along the way, we will make several stops across the booming US railroad network, traveling from viewing sites as familiar as Des Moines, Iowa, to ones as distant and strange as newly acquired Alaska.From equipment failures and botched preparations to quicksand and apocalyptic ¿comets¿, welcome to the wild, western world of solar eclipses.

Have you ever wondered what comets are and why astronomers spend so much time studying them? A comet expert and an astronomical historian have come together to produce this unique book. The authors concisely present the information you need to comprehend these majestic apparitions that grace our night skies.

Today's casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. This title gives us back our knowledge of the sky, offering an overview of what can be seen there without the help of a telescope.
