This book was released on 2013-09-26 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is a planet? The answer may seem obvious; still, the definition of a planet has continuously evolved over the centuries, and their number has changed following successive discoveries. In 2006, the decision endorsed by the International Astronomical Union to remove Pluto from the list of planets has well illustrated the difficulty associated with their definition. The recent discovery of hundreds of exoplanets around nearby stars of our Galaxy opens a new and spectacular dimension to astrophysics. We presently know very little about the physical nature of exoplanets. In contrast, our knowledge on solar system planets has made huge progress over the past decades, thanks, especially, to space planetary exploration. The purpose of this book is first to characterize what planets are, in their global properties and in their diversity. Then, this knowledge is used to try to imagine the physical nature of exoplanets, starting from the few parameters we know about them. Throughout, we keep in mind the ultimate question of the search for possible extraterrestrial life: Could life exist or have existed in the solar system and beyond?Thérèse Encrenaz is Emeritus Senior Scientist at the Centre National de la Recherche Scientifique. She works at the Observatoire de Paris, at the Laboratoire d'Etudes Spatiales et d'Instrumentation en Astrophysique (LESIA). She is a specialist of the study of planetary atmospheres, and has been involved in several space missions.

Download or read book Mirror Earth written by Michael D. Lemonick and published by Bloomsbury Publishing USA. This book was released on 2012-10-16 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The message had seemed simple, yet it was more complex than Don could have imagined. He was being called from Earth to an alien world for reasons unknown¾save only that his life depended on it. But setting out for Mars and getting there in good shape turned out to be a lot more complicated than Don ever would have guessed possible. It was trouble enough being inexplicably hounded by Earth's secret police. But when he was hijacked by Venusian rebels, Don suddenly realized that he was trapped in the center of a war between worlds that could change the fate of the Solar System forever!

Download or read book Strange New Worlds written by Ray Jayawardhana and published by Princeton University Press. This book was released on 2013-04-21 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: An insider's look at the cutting-edge science of today's planet hunters In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets—and alien life—beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars—thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own—that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths—rocky planets with several times the mass of our own planet—and how astronomers use biomarkers to seek possible life on other worlds. Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research. In a new afterword, Jayawardhana explains some of the most recent developments as we search for the first clues of life on other planets.

Download or read book The Planet Factory written by Elizabeth Tasker and published by Bloomsbury Publishing. This book was released on 2017-09-07 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forget about rockets to Mars – the future of space science lies with the search for exoplanets Twenty years ago, the search for planets outside the Solar System was the preserve of science-fiction writers. Now it's one of the fastest-growing fields in astronomy, with thousands of exoplanets discovered to date, and the number rising fast. These new-found worlds are more alien than anything in fiction. Planets larger than Jupiter with years lasting a week; others with two suns lighting their skies, or with no sun at all. Planets with diamond mantles supporting oceans of tar; possible Earth-sized worlds with split hemispheres of perpetual day and night; waterworlds drowning under global oceans and volcanic lava planets awash with seas of magma. The discovery of this diversity is just the beginning. There is a whole galaxy of possibilities. The Planet Factory tells the story of these exoplanets. What can we learn about these faraway surface environments and planetary atmospheres? And do the results hint at the tantalising possibility of alien life?
Download or read book What s So Special about Planet Earth written by Robert E. Wells and published by Albert Whitman & Company. This book was released on 2009-09-01 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Move to another planet? Sounds interesting! In our imaginary spaceship, let's check out the planets in our solar system. Mercury is closest, but it has no air, and it's either sizzling hot or bitterly cold. The atmosphere on Venus is poisonous; plus, human beings would cook there. Mars might work, but you'd always have to be in a protective shelter. And if you got to the outer planets, you couldn't even land as they are mostly made of gas! Our home planet is looking good. Why is Earth so comfortable for plants, animals, and people? As Robert E. Wells explains, it's because of our just-right position form the sun, marvelous atmosphere, and abundant water. Our planet is very special and perfect for us, and that's why we must do all we can to keep Earth healthy.

Download or read book Beyond Earth written by Charles Wohlforth and published by Vintage. This book was released on 2017-10-17 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are at the cusp of a golden age in space science, as increasingly more entrepreneurs—Elon Musk, Richard Branson, Jeff Bezos—are seduced by the commercial potential of human access to space. But Beyond Earth does not offer another wide-eyed technology fantasy: instead, it is grounded not only in the human capacity for invention and the appeal of adventure, but also in the bureaucratic, political, and scientific realities that present obstacles to space travel—realities that have hampered NASA's efforts ever since the Challenger disaster. In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars, but Titan—a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy—offers the most realistic, and thrilling, prospect of life without support from Earth.
Download or read book Destiny Or Chance written by Stuart Ross Taylor and published by Cambridge University Press. This book was released on 2000-10-25 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by a leading planetary scientist, this engaging book tells the remarkable story of how our solar system came into existence and provides an expert tour of the Earth, its planetary neighbors and other planetary systems. In a whirlwind adventure, we explore how the formation of mighty Jupiter dominated the solar system, why Mars is so small, where comets come from, how rings form around planets, why asteroids exist and why Pluto isn't a planet at all. En route, we discover the role of chance events in shaping the course of the history of our solar system. Dramatic collisions, for example, caused the tilts and spins of the planets, the extinction of the dinosaurs and the rise of man. Finally, we look at how suitable Earth is for harboring life, what other planetary systems look like and whether we are alone in the cosmos. For all those interested in understanding our solar system and its place in the cosmos, this is a lucid and compelling read. Stuart Taylor is the recipient of numerous academic awards, including the Norman L. Bowen Award from the American Geophysical Union for his important contributions to our understanding of the origins and early history of the Earth and Moon. In 1997, Asteroid 5670 was named Rosstaylor in his honor. He is the author of Solar System Evolution (Cambridge, 1992).

Available in PDF, EPUB and Kindle. Book excerpt: "Tender and illuminating. A beautiful debut." --Rebecca Stead, Newbery Medal-winning author of When You Reach Me A heartrending and hopeful debut novel about a nonverbal girl and her passion for space exploration, for fans of See You in the Cosmos, Mockingbird, and The Thing About Jellyfish. Twelve-year-old Nova is eagerly awaiting the launch of the space shuttle Challenger--it's the first time a teacher is going into space, and kids across America will watch the event on live TV in their classrooms. Nova and her big sister, Bridget, share a love of astronomy and the space program. They planned to watch the launch together. But Bridget has disappeared, and Nova is in a new foster home. While foster families and teachers dismiss Nova as severely autistic and nonverbal, Bridget understands how intelligent and special Nova is, and all that she can't express. As the liftoff draws closer, Nova's new foster family and teachers begin to see her potential, and for the first time, she is making friends without Bridget. But every day, she's counting down to the launch, and to the moment when she'll see Bridget again. Because Bridget said, "No matter what, I'll be there. I promise."
Download or read book Planet Hunter written by Vicki O. Wittenstein and published by . This book was released on 2010 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: He has discovered more planets than anyone in history. In this inspiring true story, winner of the American Institute of Physics Award, Geoff Marcy's love of space helped him overcome struggles in his studies until finally he became an astronomer. But he was not on track to make major discoveries. Eventually, he went back to the questions that thrilled him as a boy: Are we alone? Do Earth-like planets orbit the stars in the night sky? It would not be easy to find a planet outside our solarsystem. Others had tried and failed. But Marcy never gave up. Since 1995, he and his colleagues have discovered nearly half of the 380 known "extrasolar" planets. Stunning paintings transport the reader to the exotic worlds that he and others have found.
