从太空看地球之美：NASA新书用遥感影像展现家园星球

swirling white clouds, deep blue oceans and multicolored landscapes bring to life the pages of NASA’s new 168-page book “Earth,” a collection of dramatic images captured by Earth-observing satellites. 50 years ago, astronauts left Earth’s orbit for the first time and looked back at our “blue marble.” All of these years later, as we continue to send spacecraft and point our telescopes past the outer edges of the solar system, as we study our planetary neighbors and our Sun in exquisite detail, there remains much to see and explore at home. We are still just getting to know Earth through the tools of science. For centuries, painters, poets, philosophers, and photographers have sought to teach us something about our home through their art. This book stands at an intersection of science and art. From its origins, NASA has studied our planet in novel ways, using ingenious tools to study physical processes at work—from beneath the crust to the edge of the atmosphere. We chose these images because they inspire. They tell a story of a 4.5-billion-year-old planet where there is always something new to see. – Michael Carlowicz From a lava field in Iceland to the icy Patagonian landscape of South America, the 69 images in “Earth” present our home planet’s atmosphere, water, land, and ice and snow with short explanations of the science behind each image. “The spectacular images in this book remind us of the majestic beauty of our world,” said Lawrence Friedl, program director for the Applied Sciences Program in NASA’s Science Mission Directorate, Earth Science Division in Washington. “We hope these images inspire everyone to explore, understand, and appreciate the planet we call home.” NASA brings together technology, science, and unique global Earth observations to provide societal benefits and strengthen our nation. The agency makes its Earth observations freely and openly available to those seeking solutions to important global issues such as changing freshwater availability, food security and human health. The 170 page book with breath taking high resolution images is available in a variety of different formats including a hardcover edition, a free downloadable e-book (mobi / epub / pdf), and as an online with interactive features.
