Astronomy for beginners — Reading Companion

From Astrology to the Solar System

The table of contents lists 'Astrology' as the second section, immediately after the introductory remarks. This placement suggests Carrington intended to distinguish astronomy from its pseudoscientific predecessor, though the excerpts do not reveal his treatment of astrology. The solar system section follows, with individual chapters on the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and the minor planets. Carrington also includes a speculative chapter titled 'Are There Other Planets?'—a question that, given the 1925 publication date, predates the discovery of Pluto (1930). The excerpts do not provide his answer, but the inclusion indicates a willingness to engage with open scientific questions.

Stars: Fixed, Double, Colored, and Variable

Carrington devotes several chapters to stellar phenomena. He explains that 'fixed' stars are not truly stationary but appear so due to immense distances. Double stars, he notes, often appear single to the naked eye but resolve into pairs or multiples through telescopes; some form physical systems called binaries. Colored stars exhibit complementary colors—larger stars reddish or orange, smaller ones bluish-green—while planets reflect light and thus color differently (Venus white, Mars reddish). Variable stars change in brilliance, with some regular (like Omicron, period 331 days 8 hours) and others irregular. Carrington's descriptions are concise, relying on specific examples and avoiding mathematical complexity.

Beyond Stars: Comets, Nebulae, and the Milky Way

The excerpts include chapters on comets, nebulae, the Milky Way, and the number of stars. Carrington estimates that many stars are 'one, two, three and perhaps five hundred thousand light-years distant,' inviting readers to calculate the miles themselves. He also covers the position and movement of our solar system, distances and temperatures of stars, and star groups or clusters. The breadth is striking: the book moves from the solar system to the galaxy to cosmology, then abruptly shifts to terrestrial phenomena like tides, thunder, lightning, fireballs, atmospheric electricity, and the aurora borealis. This eclectic mix suggests Carrington aimed to provide a comprehensive overview of 'popular astronomy' as understood in the 1920s.

Carrington's book is best approached as a snapshot of early 20th-century astronomical knowledge, filtered through a philosophical lens. Readers should note that the excerpts omit many sections (e.g., telescopes, spectroscope, photography, calendars, curved space), so the full text likely contains further technical detail. The author's habit of posing unanswered questions—like 'Are the Planets Inhabited?'—invites curiosity rather than closure. For a modern reader, the value lies not in current accuracy but in observing how a 1925 primer balanced science, speculation, and wonder.

Years ago, I held Carrington’s dear primer, feeling its gentle lesson of our smallness beneath the stars. That same hush lingers in the memoir of Herschel, who listened to the heavens so patiently. It is a quiet kinship, two voices across time, sharing one awed glance upward. Sir William Herschel: His Life and Works — Context and Discussion sits beside it now, like an old friend nodding in agreement.
