Meteorites


Book Description

"A well-illustrated overview of the science and (literal) impact of these space rocks." -- Science News, on the first edition Leading experts in the field provide a compelling introduction to the space rocks that enter Earth's atmosphere at speeds ranging from 25,000 mph to 160,000 mph. Scientists estimate that about 48.5 tons of meteoritic material falls on the Earth each day. These messengers from space give us a unique insight into the nature of the material that was present when our solar system formed. Many of the specimen meteorites in this second edition were re-photographed to improve quality, and the optical microscopy shots were updated. There is also much new information on discoveries and developments in the study of meteorites, including: Meteorite falls and craters, and new information on ones previously covered Use of weather radar to detect and analyze meteorites, such as the 28,000 mph January 18, 2018, Michigan "fireball" How astrophysicists determine if a meteorite comes from Mars, and information about the Martian meteorites found to date Updated information on the results of the European Space Agency's Rosetta Mission in which a controlled impact was successfully completed into Comet 67P after investigating it with a probe for more than two years. Co-author Sara Russell, who is part of NASA's Mars program, provides the latest news about NASA's Mars programs, including the Mars Rover, which landed in 2016.




Meteorite


Book Description

Among the rarest things on earth, meteorites carry an air of mystery and drama while having left a pervasive, outsized mark on our planet and civilization. In Meteorite, Maria Golia tells the long history of our engagement with these sky-born space rocks. Arriving amid thunderous blasts and flame-streaked skies, meteorites were once thought to be messengers from the gods. Worshipped in the past, now scrutinized with equal zeal by scientists, meteorites helped sculpt Earth’s features and have shaped our understanding of the planet’s origins. Prized for their outlandish qualities, meteorites are a collectible and a commodity, objects of art and artists’ desires and a literary muse; and ‘meteorite hunting’ is an adventurous, lucrative profession for some and an addictive hobby for thousands of others. A richly illustrated, remarkably wide-ranging account of the culture and science surrounding meteorites, Golia’s book explores the ancient, lasting power of the meteorite to inspire and awe.

Meteorite


Book Description

Explore the universe and immerse yourself in the story of our solar system, planet, and life through meteorites. "Meteorite is a treasure"--Wall Street Journal Meteorites have long been seen as portents of fate and messages from the gods, their fiery remains inspiring worship and giving rise to legends that have persisted for millennia. But beyond the lore, meteorites tell an even greater story: that of our solar system. In Meteorite, geologist Tim Gregory shows that beneath the charred crusts of these celestial stones lies a staggering diversity of rock types. Their unique constituents, vibrant colors, and pungent smells contain thrilling tales of interstellar clouds, condensing stardust, and the fiery collisions of entire worlds. Gregory explores the world of meteorites to uncover new insights into what our solar system was like before our sun became a star, into the forging of our planet, and into the emergence of life on it. Humans have long looked to the skies for answers to big questions. Meteorite reveals how science is finally arriving at those answers.




Mysteries of Meteors, Asteroids, and Comets


Book Description

What are asteroids, comets, and meteors made of? What can scientists do if an asteroid is headed toward Earth? Learn how astronomers prepare for space objects hitting Earth, from tracking them to building asteroid-hunting telescopes. Budding astronomers will learn all about meteors, asteroids, and comets, including the history of asteroids hitting Earth and the differences between space rocks.




Meteorites, Ice, and Antarctica


Book Description

Bill Cassidy has led meteorite recovery expeditions in the Antarctic for many years. His searches have resulted in the collection of thousands of meteorite specimens from the ice. This fascinating story is a first-hand account of his field experiences on the US Antarctic Search for Meteorites Project, which he carried out as part of an international team of scientists. Cassidy describes this hugely successful field program in Antarctica and its influence on our understanding of the moon, Mars and the asteroid belt. In this 2003 book, he describes the hardships and dangers of fieldwork in a hostile environment, as well as the appreciation he developed for the beauty of the place. In the final chapters he speculates on the results of the trips and the future research they might lead to.







The Mystery of the Seven Spheres


Book Description

In this book, Giovanni Bignami, the outstanding Italian scientist and astronomer, takes the reader on a journey through the “seven spheres”, from our own planet to neighboring stars. The author offers a gripping account of the evolution of Homo Sapiens to the stage where our species is developing capabilities, in the form of new energy propulsion systems, that will enable us to conquer space. The reader will learn how we first expanded our activities to reach beyond our planet, to the Moon, and how nuclear energy, nuclear fusion, and matter–antimatter annihilation will enable us to extend our exploration. After Mars and Jupiter we shall finally reach the nearest stars, which we now know are surrounded by numerous planets, some of which are bound to be habitable. The book includes enticing descriptions of such newly discovered planets and also brings alive key historical characters in our story, such as Jules Verne and Werner von Braun.




In Search of Stardust


Book Description

In Search of Stardust is the first comprehensive popular science book about micrometeorites. It's illustrated with 1,500 previously unpublished images from high-resolution color microscopes and scanning electron microscopes.




Familiars in Witchcraft


Book Description

A comprehensive exploration of familiars and their many forms and powers • Explores witch’s familiars in folklore, shamanic, and magical traditions around the world, including Africa, India, Scandinavia, ancient Greece, and China • Explains how familiars are related to shamanic power animals and how the witch draws on her personal sexual energy to give this creature its power • Examines the familiar in alchemical, Hermetic, and Egyptian magical literature, including instructions for procuring a supernatural assistant Exploring the history and creation of a “witch’s familiar,” also known as a spirit double or guardian spirit, Maja D’Aoust shows how there is much more to these supernatural servant spirits and guardians than meets the eye. She reveals how witches are not the only ones to lay claim to this magician’s “assistant” and examines how the many forms of witch’s familiars are well known in folklore throughout Europe and America as well as in shamanic and magical traditions around the world, including Africa, India, and China. The author explains how familiars are connected with shapeshifting and how the classic familiars of medieval witchcraft tradition are related to the power animals and allies of shamanic practices worldwide, including animal guardian spirits of Native American traditions and the daimons of the ancient Greeks and Romans. She examines the fetch spirit, also known as the fylgia in Scandinavian tradition, and how the witch or sorcerer draws on their personal sexual energy to give this creature its power to magnetize and attract what it was sent to retrieve. She looks at incubus, succubus, doubles, doppelgangers, and soul mates, showing how familiars can also adopt human forms and sometimes form romantic or erotic attachments with the witch or shaman. Reviewing alchemical, Hermetic, and Egyptian magical literature, including the nearly forgotten alchemical works of Anna Kingsford, D’Aoust explores their instructions for procuring the attention of a supernatural assistant as well as an extensive description of the alchemical wedding and how this ritual joins the magician and familiar spirit into a single unified consciousness. Exploring fairy familiars, she reveals how a practitioner can establish a “marriage” with a totemic plant or tree spirit, who, in return, would offer teachings about its medicinal and visionary powers. Delving deeply into the intimate relations of humanity with the spirit world, D’Aoust shows how forming connections with living forces other than human enables us to move beyond the ego, expand our magical abilities, as well as evolve our conscious awareness.
