Book Description
One of the most ambitious works of paranormal investigation of our time, here is an unprecedented compendium of pre-twentieth-century UFO accounts, written with rigor and color by two of today's leading investigators of unexplained phenomena. In the past century, individuals, newspapers, and military agencies have recorded thousands of UFO incidents, giving rise to much speculation about flying saucers, visitors from other planets, and alien abductions. Yet the extraterrestrial phenomenon did not begin in the present era. Far from it. The authors of Wonders in the Sky reveal a thread of vividly rendered-and sometimes strikingly similar- reports of mysterious aerial phenomena from antiquity through the modern age. These accounts often share definite physical features- such as the heat felt and described by witnesses-that have not changed much over the centuries. Indeed, such similarities between ancient and modern sightings are the rule rather than the exception. In Wonders in the Sky, respected researchers Jacques Vallee and Chris Aubeck examine more than 500 selected reports of sightings from biblical-age antiquity through the year 1879-the point at which the Industrial Revolution deeply changed the nature of human society, and the skies began to open to airplanes, dirigibles, rockets, and other opportunities for misinterpretation represented by military prototypes. Using vivid and engaging case studies, and more than seventy-five illustrations, they reveal that unidentified flying objects have had a major impact not only on popular culture but on our history, on our religion, and on the models of the world humanity has formed from deepest antiquity. Sure to become a classic among UFO enthusiasts and other followers of unexplained phenomena, Wonders in the Sky is the most ambitious, broad-reaching, and intelligent analysis ever written on premodern aerial mysteries.

Lights in the Sky

Lights in the Sky PDF Author: Michael Maunder
Publisher: Springer Science & Business Media
ISBN: 1846287618
Category : Science
Languages : en
Pages : 233

Book Description
Many lights and other objects in the sky go unrecognised, or at least are little understood by those observing them. Such things range from the commonplace like rainbows and meteors, to the distinctly unusual like the green flash and ball lightning. And there is still a residuum of objects that remain unidentified by the watcher – classed generally as ‘UFOs’, a description which today has connotations of the mysterious, even of extraterrestrial visitors. The first part of this book is an identification guide, very much like the "plant identifier" sections found in a good gardening or botany book. It allows quick (and structured) identification of known aerial phenomena, whether at night or during the day. The objects thus found are referenced to the second part of the book... The second part gives a full description, physical explanation, and where relevant notes on observing and photographing the various phenomena. Some will need optical aids such as binoculars or telescopes, but the main thrust of the book is identification and explanation rather than imaging. The final chapter approaches UFOs from a scientific standpoint, particularly the way in which human perception and often preconception affects the outcome. It does however finish with a short section on "extraterrestrial UFOs", emphasising the burden of proof aspect and touching on the scientific theories of life on other worlds and the improbability of visitors.
