A Popular History of Astronomy During the Nineteenth Centuryfourth Edition

In the nineteenth century, the cosmos transformed from eternal, unchanging pinpricks of light into burning, evolving worlds of staggering diversity. Agnes M. Clerke, the remarkable self-taught astronomer who commanded respect from the era's greatestobservatories, chronicles this complete revision of everything humanity thought it knew. Here is the story of spectroscopy splitting starlight into secrets, of Herschel peering into the depths of creation and finding it stranger than anyone imagined, of nebulae that blurred the line between clouds of gas and island universes. Clerke writes not as a distant chronicler but as someone who lived inside this revolution, who knew the astronomers wrestling with these discoveries and understood what each new observation meant for humanity's place in the scheme of things. This is popular science at its finest: rigorous, awestruck, and deeply human. The fourth edition captures a century's worth of progress in understanding the stars, told by someone who helped make some of that progress visible to the reading public.
