The Evolution of Worlds

In this landmark work from 1909, Percival Lowell turns his gaze from Mars to the grand canvas of cosmic evolution itself. Drawing on his lifetime of astronomical observation and theoretical speculation, Lowell constructs a sweeping narrative of how solar systems are born, how planets transform over eons, and how cataclysmic forces reshape celestial bodies. The book reflects both the brilliance and the blindspots of early twentieth-century astronomy: here is a man who saw the universe as a dynamic, living system, still years away from understanding the true mechanisms of stellar and planetary formation. For modern readers, the work serves as a fascinating artifact of scientific history, revealing how one of astronomy's most controversial figures grappled with questions of cosmic time, planetary destiny, and humanity's place in an evolving universe. Lowell enthusiasts and history-of-science readers will find here the intellectual machinery behind the man who famously mapped non-existent canals on the red planet.
