Toote kirjeldus: Fire in the Sky: Cosmic Collisions, Killer Asteroids, and the Race to Defend Earth

"An historical survey about asteroid hits sustained by Earth and the defenses being prepared against future asteroid-caused catastrophe"--
Combines history, pop science, and in-depth reporting in a chronicle of the role of asteroid collisions in Earth's evolution and how scientists are preparing for the next impact catastrophe.
This &;accessible and always entertaining&; (Booklist) combination of history, pop science, and in-depth reporting offers a fascinating account of the asteroids that hit Earth long ago and those streaming toward us now, as well as how prepared we are against asteroid-caused catastrophe.One of these days, warns Gordon Dillow, the Earth will be hit by a comet or asteroid of potentially catastrophic size. The only question is when. In the meantime, we need to get much better at finding objects hurtling our way, and if they&;re large enough to penetrate the atmosphere without burning up, figure out what to do about them. We owe many of science&;s most important discoveries to the famed Meteor Crater, a mile-wide dimple on the Colorado Plateau created by an asteroid hit 50,000 years ago. In his masterfully researched Fire in the Sky, Dillow unpacks what the Crater has to tell us. Prior to the early 1900s, the world believed that all craters&;on the Earth and Moon&;were formed by volcanic activity. Not so. The revelation that Meteor Crater and others like it were formed by impacts with space objects has led to a now accepted theory about what killed off the dinosaurs, and it has opened up a new field of asteroid observation that is brimming with urgency. Dillow looks at great asteroid hits of the past and modern-day asteroid hunters and defense planning experts, including America&;s first Planetary Defense Officer. Satellite sensors confirm that a Hiroshima-scale blast occurs in the atmosphere every year, and a smaller, one-kiloton blast every month. While Dillow makes clear that the objects above can be deadly, he consistently inspires awe with his descriptions of their size, makeup, and origins. Both a riveting work of popular science and a warning to not take for granted the space objects hurtling overhead, Fire in the Sky is, ultimately, a testament to our universe&;s celestial wonders.
