It all happened because of Feeney's Original Astronaut Ice Cream. Those accursed pink bars entranced me with their sugary magic! Life on Gelo was fine until the fur-headed "humans" arrived. They invaded our asteroid with their loud drill machines and their endless greed, stealing our precious iridium to take back to their weird-looking blue-and-green planet. Then the mothership took off and four little fur-heads were marooned here. Luckily, the "kids" have cool things like hologram games and rocket bikes. And they know how to pilot starships! But there's plenty the junior humans don't know, like how to fight a feral thyss-cat or ride an usk-lizard. They're decidedly terrible at dealing with my stink gland (yes, we Xotonians have a stink gland). And they definitely seem powerless against the Vorem, a terrifying breed of rival alien that nightmares are made of. Thank goodness the Earthlings have me and all five of my eyes to look after them! If only I knew how to help them get back home. . . .
Describes the role that collisions with meteors, comets, and asteroids have played in the history of Earth and other planets in the solar system and examines what is being done to protect Earth from future collisions.
A Short History of Nearly Everything meets Astrophysics for People in a Hurry in this humorous, accessible exploration of how meteorites have helped not only build our planet but steered the evolution of life and human culture. The Solar System. Dinosaurs. Donkey Kong. What is the missing link? Surprisingly enough, it's meteorites. They explain our past, constructed our present, and could define our future. Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth’s early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet. While meteorites have provided the raw materials for life to thrive, they have radically devastated life as well, most famously killing off the dinosaurs and paving the way for humans to evolve to where we are today. As noted meteoriticist Greg Brennecka explains, meteorites did not just set us on the path to becoming human, they helped direct the development of human culture. Meteorites have influenced humanity since the start of civilization. Over the centuries, meteorite falls and other cosmic cinema have started (and stopped) wars, terrified millions, and inspired religions throughout the world. With humor and an infectious enthusiasm, Brennecka reveals previously untold but important stories sure to delight and inform readers about the most important rocks on Earth.
"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.
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.
In this riveting book, acclaimed journalist Kathy Sawyer reveals the deepest mysteries of space and some of the most disturbing truths on Earth. The Rock from Mars is the story of how two planets and the spheres of politics and science all collided at the end of the twentieth century. It began sixteen million years ago. An asteroid crashing into Mars sent fragments flying into space and, eons later, one was pulled by the Earth’s gravity onto an icy wilderness near the southern pole. There, in 1984, a geologist named Roberta Score spotted it, launching it on a roundabout path to fame and controversy. In its new home at NASA’s Johnson Space Center in Houston, the rock languished on a shelf for nine years, a victim of mistaken identity. Then, in 1993, the geochemist Donald “Duck” Mittlefehldt, unmasked the rock as a Martian meteorite. Before long, specialist Chris Romanek detected signs of once-living organisms on the meteorite. And the obscure rock became a rock star. But how did nine respected investigators come to make such startling claims about the rock that they triggered one of the most venomous scientific battles in modern memory? The narrative traces the steps that led to this risky move and follows the rippling impact on the scientists’ lives, the future of space exploration, the search for life on Mars, and the struggle to understand the origins of life on Earth. From the second the story broke in Science magazine in 1996, it spawned waves of excitement, envy, competitive zeal, and calculation. In academia, in government agencies, in laboratories around the world, and even in the Oval Office–where an inquisitive President Clinton had received the news in secret– players of all kinds plotted their next moves. Among them: David McKay, the dynamic geologist associated with the first moon landing, who labored to achieve at long last a second success; Bill Schopf of UCLA, a researcher determined to remain at the top of his field and the first to challenge McKay’s claims; Dan Goldin, the boss of NASA; and Dick Morris, the controversial presidential adviser who wanted to use the story for Clinton’s reelection and unfortunately made sure it ended up in the diary of a $200-an-hour call girl. Impeccably researched and thrillingly involving, Kathy Sawyer’s The Rock from Mars is an exemplary work of modern nonfiction, a vivid account of the all-too-human high-stakes drive to learn our true place in the cosmic scheme.
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.
Beautifully illustrated with over 140 full colour images, The Cambridge Encyclopedia of Meteorites provides a thorough guide to these fascinating extraterrestrial rocks. Meteorites are our only contact with materials from beyond the Earth-Moon system. Using well known petrologic techniques, this book reveals in vivid colour their extraordinary external and internal structures. Looking deeper still, right to the atomic level, they begin to tell us of the environment within the solar nebula that existed before the planets accreted. In recent years, meteorites have caught the imagination of scientist and collector alike. An army of people are now actively searching for them in the hot and cold deserts of Earth. This book is a valuable guide to assist the searchers in the field to recognize the many classes of meteorites. It is further a reference source for students, teachers and scientists who wish to probe deeper these amazing rocks from space.
