After addressing strange cosmological hypotheses in Weird Universe, David Seargent tackles the no-less bizarre theories closer to home. Alternate views on the Solar System's formation, comet composition, and the evolution of life on Earth are only some of the topics he addresses in this new work. Although these ideas exist on the fringe of mainstream astronomy, they can still shed light on the origins of life and the evolution of the planets. Continuing the author's series of books popularizing strange astronomy facts and knowledge, Weird Astronomical Theories presents an approachable exploration of the still mysterious questions about the origin of comets, the pattern of mass extinctions on Earth, and more. The alternative theories discussed here do not come from untrained amateurs. The scientists whose work is covered includes the mid-20th century Russian S. K. Vsekhsvyatskii, cosmologist Max Tegmark, British astronomers Victor Clube and William Napier, and American Tom Van Flandern, a specialist in celestial mechanics who held a variety of unusual beliefs about the possibility of intelligent life having come from elsewhere. Despite being outliers, their work reveals how much astronomical understanding is still evolving. Unconventional approaches have also pushed our scientific understanding for the better, as with R.W. Mandl's approaching Einstein with regard to gravitational lensing. Even without full substantiation (and some theories are hardly credible), their hypotheses allow for a new perspective on how the Solar System became what it is today.

This fully-updated second edition remains the only truly detailed exploration of the origins of our Solar System, written by an authority in the field. Unlike other authors, Michael Woolfson focuses on the formation of the solar system, engaging the reader in an intelligent yet accessible discussion of the development of ideas about how the Solar System formed from ancient times to the present.Within the last five decades new observations and new theoretical advances have transformed the way scientists think about the problem of finding a plausible theory. Spacecraft and landers have explored the planets of the Solar System, observations have been made of Solar-System bodies outside the region of the planets and planets have been detected and observed around many solar-type stars. This new edition brings in the most recent discoveries, including the establishment of dwarf planets and challenges to the ‘standard model’ of planet formation — the Solar Nebula Theory.While presenting the most up-to-date material and the underlying science of the theories described, the book avoids technical jargon and terminology. It thus remains a digestible read for the non-expert interested reader, whilst being detailed and comprehensive enough to be used as an undergraduate physics and astronomy textbook, where the formation of the solar system is a key part of the course.Michael Woolfson is Emeritus Professor of Theoretical Physics at University of York and is an award-winning crystallographer and astronomer.

ASTRONOMY: THE SOLAR SYSTEM AND BEYOND and its accompanying learning tools CengageNOW and Virtual Astronomy Labs shows you your place in the universe, not just your location, but also your role as a planet dweller in an evolving universe. You will learn to focus on the scientific method through the strong central questioning themes of "What are we?" and "How do we know?" Rather than memorize facts, you will be empowered to create your own understanding of your place in the cosmos. Use CengageNOW to not only enhance your conceptual understanding of the content, but to improve your grade in the course.

The past few years have seen an incredible explosion in our knowledge of the universe. Since its 2009 launch, the Kepler satellite has discovered more than two thousand exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, and even more remarkable than the sheer number of exoplanets is their variety. In Exoplanets, astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space. This captivating book reveals the latest discoveries and argues that the incredible richness and complexity we are finding necessitates a change in our questions and mental paradigms. In short, we have to change how we think about the universe and our place in it, because it is stranger and more interesting than we could have imagined.

Describes the science of planet hunters, the prospects for the discovery of alien life, and discusses the controversies surrounding extrasolar-planet research.

Tracing the evolution of humankind's pursuit of astronomical knowledge, this resource looks deep into the furthest reaches of space. Children will follow along as the realization that the Earth is not at the center of the universe leads all the way up to recent telescopic proof of planets orbiting stars outside the solar system. In addition to its engaging history, this book contains 21 hands-on projects to further explore the subjects discussed. Readers will build a three-dimensional representation of the constellation Orion, see how the universe expands using an inflating balloon, and construct a reflecting telescope out of a makeup mirror and a magnifying glass. It also includes small biographies of famous astronomers, a time line of major scientific discoveries, a glossary of technical terms, and dozens of full-color images taken by the Hubble Space Telescope and the Chandra X-Ray Observatory.

"Touches on a dizzying array of subjects, including UV rays, inert gases, fossils, meteorites, microwaves, rainbows . . . Like many a good teacher, Berman uses humor to entertain his audience and liven things up." —Los Angeles Times Bob Berman is motivated by a straightforward philosophy: everyone can understand science—and it's fun, too. In Strange Universe, he pokes into the bizarre and astonishingly true scientific facts that determine the world around us. Geared to the nonscientist, Berman's original essays are filled with the trademark wit and cleverness that has earned him acclaim over many years for his columns in Astronomy and Discover magazines. He emphasizes curiosities of the natural world to which everyone can relate, and dishes on the little-known secrets about space and some of science's biggest blunders (including a very embarrassing moment from Buzz Aldrin's trip to the moon). Fascinating to anyone interested in the wonders of our world and the cosmos beyond, Strange Universe will make you smile and think.
