In the mid-1990s, astronomers made history when they began to find planets orbiting stars in the Milky Way. More than eight hundred planets have been found since then, yet none of them is anything like Earth and none could support life. Now, armed with more powerful technology, planet hunters are racing to find a true twin of Earth. Science writer Michael Lemonick has unique access to these exoplaneteers, as they call themselves, and Mirror Earth unveils their passionate quest. Unlike competitors in other races, Geoff Marcy, Bill Borucki, David Charbonneau, Sara Seager, and others actually consult and cooperate with one another. But only one will be the first to find Earth's twin. Mirror Earth tells the story of their competition.
In 1995 two Swiss astronomers discovered a planet circling a star other than our Sun. This changed our perception of the Universe forever, proving that Earth and the other celestial bodies in our Solar System are not alone in outer space. Now, after two decades of exploration, more than 860 planets have been discovered, many of which are completely unlike anything else we know. Some are blacker than coal; some are bathed in molten lava; others are perpetually scoured by hurricane-force winds; some have not one sun but two that rise in the morning, and others are perpetually drowned in global oceans. But as well as strange, uninhabitable lands, there is familiarity too. Some of these alien worlds are strikingly similar to planets in our Solar System. Astronomers now know of planets just like Jupiter, Neptune, Mars and Mercury orbiting stars similar to our Sun, both nearby and deep into space. Authoritatively written and fully up to date on this fast-moving area of science, The Search for the Earth's Twin will take you on a journey through the cosmos via frozen wastelands, slow-moving globes and fiery volcanic bodies, to planets that can - and just might - sustain complex life. The prospect of discovering the Earth's twin is now tantalisingly close.
In 1975, Putnam published a paper called The Meaning of 'Meaning', which challenged the orthodox view in the philosophies of language and mind. The article's Twin Earth conclusions about meaning, thought and knowledge were shocking. This work contains writings on the subject of Twin Earth.
_______________________ 'A comedy with teeth ... razor sharp and darkly funny' (TIMES) 'Boyle's prose is so good and his imagination so fertile that after a while you just sit back and are swept along' (TELEGRAPH) 'Surreal, daring and compassionate. Easily one of the best books of the year' (MAIL) 'Superb ... if Boyle was from this side of the pond, this is the book they'd all have to beat for the Booker Prize' (SUNDAY TIMES) It's 2025, and 75-year-old environmentalist and retired eco-terrorist Ty Tierwater is eking out a bleak living managing a pop star's private zoo. It is the last one in southern California, and vital for the cloning of its captive species. Once, Ty was so serious about environmental causes that as a radical activist committed to Earth Forever! he endangered the lives of both his daughter, Sierra, and his wife, Andrea. Now, when he's just trying to survive in a world cursed by storm and drought, Andrea re-enters his life. Frightening, funny, surreal and gripping, T.C. Boyle's story is both a modern morality tale, and a provocative vision of the future.

“How do alien, faraway worlds reveal their existence to Earthlings? Let Donald Goldsmith count the ways. As an experienced astronomer and a gifted storyteller, he is the perfect person to chronicle the ongoing hunt for planets of other stars.” —Dava Sobel Astronomers have recently discovered thousands of planets that orbit stars throughout our Milky Way galaxy. With his characteristic wit and style, Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that Earthlings with little background in astronomy or astrophysics can understand and enjoy. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds, which bear little resemblance to the planets in our solar system. The sizes, masses, and orbits of exoplanets detected so far raise new questions about how planets form and evolve. Still more tantalizing are the efforts to determine which exoplanets might support life. Astronomers are steadily improving their means of examining these planets’ atmospheres and surfaces, with the help of advanced spacecraft sent into orbits a million miles from Earth. These instruments will provide better observations of planetary systems in orbit around the dim red stars that throng the Milky Way. Previously spurned as too faint to support life, these cool stars turn out to possess myriad planets nestled close enough to maintain Earthlike temperatures. The quest to find other worlds brims with possibility. Exoplanets shows how astronomers have broadened our planetary horizons, and suggests what may come next, including the ultimate discovery: life beyond our home planet.
Describes the science of planet hunters, the prospects for the discovery of alien life, and discusses the controversies surrounding extrasolar-planet research.
For the first time in human history, we know for certain the existence of planets around other stars. Now the fastest-growing field in space science, the time is right for this fundamental source book on the topic which will lay the foundation for its continued growth. Exoplanets serves as both an introduction for the non-specialist and a foundation for the techniques and equations used in exoplanet observation by those dedicated to the field.
When humanity first glimpsed planet Earth from space, the unity of the system that supports humankind entered the popular consciousness. The concept of the Earth's atmosphere, biosphere, oceans, soil, and rocks operating as a closely interacting system has rapidly gained ground in science. This new field, involving geographers, geologists, biologists, oceanographers, and atmospheric physicists, is known as Earth System Science. In this Very Short Introduction, Tim Lenton considers how a world in which humans could evolve was created; how, as a species, we are now reshaping that world; and what a sustainable future for humanity within the Earth System might look like. Drawing on elements of geology, biology, chemistry, physics, and mathematics, Lenton asks whether Earth System Science can help guide us onto a sustainable course before we alter the Earth system to the point where we destroy ourselves and our current civilisation. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
