Combining history, pop science, and in-depth reporting, a
fascinating account of asteroids that hit Earth long ago, and those
streaming toward us now, as well as how we are preparing 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, which has recently brimmed with urgency. Dillow looks
at great asteroid hits of the past and spends time with 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. At once a
riveting work of popular science and a warning to not take for
granted the space objects hurtling overhead, Fire in the Sky is,
above all, a testament to our universe's celestial wonders.
