Are we alone in the Universe? From the furor over Percival Lowell's claim of canals on Mars at the beginning of the century to the more recent controversial rock from Mars and the sophisticated Search for Extraterrestrial Intelligence (SETI), the prospect of otherworldly life has often titillated and occasionally consumed science and the public. The search for planetary systems, the quest to explain UFOs, and inquiries into the origin of life have fueled an abundance of popular and scientific literature. They have also provided Hollywood with fodder for some of the most popular films of our time, including ET, Aliens, Independence Day, and Contact. Lucid and accessible, Life on Other Worlds chronicles the history of the twentieth-century extraterrestrial debate. Putting the latest findings and heated controversies into a broader historical context, Steven Dick documents how the concept of extraterrestrial intelligence is a world view of its own--a "biophysical cosmology" that seeks confirmation no less than physical views of the Universe. The debate rests at the very limits of science, and attempts at confirmation only illuminate the nature of science itself. Dick shows that appreciating the history of the debate enables a better understanding of the nature of science, and is central to any forward-looking view of religion and philosophy. For anyone interested in a look over the edge of scientific discovery, Life on Other Worlds provides the exciting tale behind the greatest debate in the twentieth century. Dr. Steven J. Dick is an astronomer and historian of science at the U.S. Naval Observatory. He is the author of Plurality of Worlds: The Origins of the Extraterrestrial Life Debate from Democritus to Kant (Cambridge, 1982) and Biological Universe (Cambridge, 1996).

In The Search for Life on Other Planets, Jakosky offers a scientific foundation for thinking there may be life elsewhere in the Universe. Using the early history of the Earth and the conditions that would allow life to exist, he creates a sound, scientific foundation for the possibility of life on planets other than our own. Jakosky integrates the mechanics of planets and recent findings from our planetary exploration program to create a rich and accessible look at the likelihood of extraterrestrials and the possibility of life on other planets. His prose is authoritative but avoids technical jargon and is well illustrated throughout. For all those interested in understanding the scientific evidence for and likelihood of extraterrestrial life, this is the most comprehensive and readable book to date. Bruce Jakosky is active in spacecraft observations, and has been involved with the Viking, Solar Mesosphere Explorer, Clementine, Mars Observer, and Mars Global Surveyor missions. Currently, he teaches both undergraduate and graduate courses in terrestrial and planetary geology at the University of Colorado, Boulder.

If only the war had lasted another six months, then Hitler would have won ... because his scientists stood upon the very brink of inventing flying saucers. That, at least, is the myth as it is currently being peddled today, in books, pamphlets and online; and, if it were true, squadrons of Luftwaffe spacecraft would certainly have made mincemeat out of British Spitfires and American B-52s. But, of course, it is a complete fiction. And yet the sinister myth of Nazi UFOs is surprisingly well developed. If you listen to its champions, escaped Nazis and their indoctrinated offspring are simply hiding in secret Antarctic bases, inside the Hollow Earth, somewhere upon another planet, or even within another dimension, just waiting for the right time to strike again - and this time, armed with saucers and in close alliance with Aryans from other star systems, they stand poised to finish what they started. Some even claim that Hitler and his chief henchmen did not really die in 1945, but were borne away in spirit on flying saucers. Such theories seem insane - but do they have a hidden purpose? White supremacists around the globe have adopted Nazi ufology to draw the gullible into the wider orbit of Far-Right ideology; after all, if the standard version of history is so wrong as to fail to acknowledge that Hitler helped invent UFOs, then what else might historians have got wrong about the Third Reich? Might the Nazis actually have been right all along? Could the Holocaust have been a total hoax? Once they have swallowed the first lie, a person might easily swallow several others. The stories in this book are bizarre: Nazi saucer-pilots fighting alongside Saddam Hussein in the first Gulf War; alien boot-prints whose soles bear swastikas being found in the wake of UFO-landings; the leader of America's Nazi Silvershirts claiming to be in psychic contact with men from other galaxies; and Allied pilots being buzzed by fiery glowing 'foo fighters' during the Second World War. They may seem harmless at first, but they are not. Is it really the white race's destiny to conquer the icy reaches of space under the banner of the 'Aryan world spirit'? Perhaps not, but the conquest of their victims' inner space, not outer space, in the name of Hitlerism is what these latter-day Goebbels truly desire.
