About This Book

The author surveys a wide range of astronomical phenomena, translating technical observations into plain language while retaining scientific accuracy. Chapters examine dark voids within the Milky Way, star clusters and migrations, the slow alteration of constellations, and the varied forms of nebulae including spirals and whirlpools. Other sections describe transient stars, solar surroundings, the zodiacal light, auroral displays, and the behavior and transformations of comets, meteors, and meteorites. The work also addresses catastrophic lunar features, questions about Mars and its canals, and the origin and fate of the asteroids, illustrated with many plates and charts.

PREFACE

What Froude says of history is true also of astronomy: it is the most impressive where it transcends explanation. It is not the mathematics of astronomy, but the wonder and the mystery that seize upon the imagination. The calculation of an eclipse owes all its prestige to the sublimity of its data; the operation, in itself, requires no more mental effort than the preparation of a railway time-table.

The dominion which astronomy has always held over the minds of men is akin to that of poetry; when the former becomes merely instructive and the latter purely didactic, both lose their power over the imagination. Astronomy is known as the oldest of the sciences, and it will be the longest-lived because it will always have arcana that have not been penetrated.

Some of the things described in this book are little known to the average reader, while others are well known; but all possess the fascination of whatever is strange, marvelous, obscure, or mysterious—magnified, in this case, by the portentous scale of the phenomena.

The idea of the author is to tell about these things in plain language, but with as much scientific accuracy as plain language will permit, showing the wonder that is in them without getting away from the facts. Most of them have hitherto been discussed only in technical form, and in treatises that the general public seldom sees and never reads.

Among the topics touched upon are:

  • The strange unfixedness of the “fixed stars,” the vast migrations of the suns and worlds constituting the universe.
  • The slow passing out of existence of those collocations of stars which for thousands of years have formed famous “constellations,” preserving the memory of mythological heroes and heroines, and perhaps of otherwise unrecorded history.
  • The tendency of stars to assemble in immense clouds, swarms, and clusters.
  • The existence in some of the richest regions of the universe of absolutely black, starless gaps, deeps, or holes, as if one were looking out of a window into the murkiest night.
  • The marvelous phenomena of new, or temporary, stars, which appear as suddenly as conflagrations, and often turn into something else as eccentric as themselves.
  • The amazing forms of the “whirlpool,” “spiral,” “pinwheel,” and “lace,” or “tress,” nebulæ.
  • The strange surroundings of the sun, only seen in particular circumstances, but evidently playing a constant part in the daily phenomena of the solar system.
  • The mystery of the Zodiacal Light and the Gegenschein.
  • The extraordinary transformations undergone by comets and their tails.
  • The prodigies of meteorites and masses of stone and metal fallen from the sky.
  • The cataclysms that have wrecked the moon.
  • The problem of life and intelligence on the planet Mars.
  • The problematical origin and fate of the asteroids.
  • The strange phenomena of the auroral lights.

An attempt has been made to develop these topics in an orderly way, showing their connection, so that the reader may obtain a broad general view of the chief mysteries and problems of astronomy, and an idea of the immense field of discovery which still lies, almost unexplored, before it.
