About This Book
A scientific survey of whether other worlds could support life, combining observational reports and physical reasoning. The author examines the nature of living organisms and the Sun’s influence, evaluates elemental distribution in space, and reviews telescopic evidence about the Moon, Mars (including reported canals and possible optical illusions), Venus, Mercury, the asteroids, and the major planets. He discusses planetary cooling and thermal histories, compares claimed surface or seasonal changes with effects of illumination and instrument limits, and weighs theoretical and empirical arguments before offering a measured conclusion on the likelihood that other planets might harbor living organisms.
