In 2016 I was enjoying an early morning cup of coffee on my back porch in Arizona when an eerie red light lit up the dark sky, followed seconds later by a tremendous distant explosion that rattled my cup and set my dogs howling. As a soldier and journalist, I had seen all kinds of human and natural catastrophes and mayhem, but never anything like this. Later I was astonished to learn that this event, which was seen as far away as Texas, was caused by a small asteroid the size of a refrigerator that had exploded in the atmosphere with the energy equivalent of a million pounds of TNT. I wanted to find out more – and I did.

Fire in the Sky: Cosmic Collisions, Killer Asteroids, and the Race to Defend Earth
From its earliest formation our planet has been routinely bombarded by space rocks large and small. In fact, collisions between small asteroids and Earth are a daily occurrence. Fortunately, most of the small ones burn up in the atmosphere, and the big ones don’t come around very often. But the question isn’t if another large asteroid or comet will strike the Earth with catastrophic consequences -- the only question is when. It could be a thousand years from now, or it could be next Tuesday. Fire in the Sky takes an accessible and sometimes light-hearted look at the history of these space invaders -- including the six-mile wide asteroid that wiped out the dinosaurs 66 million years ago -- as well as the ongoing efforts to identify, and if possible deflect, large asteroids that may threaten our planet in the future.
The subtitle of this book says it all. As a planetary scientist for NASA’s Jet Propulsion Laboratory, Yeomans’ job was to plot the courses of known and newly-discovered NEOs – that is, asteroids and comets that in space terms come close to Earth’s orbit – and determine if and when they might be on a collision course with our planet. With more than 25,000 known NEOs orbiting around up there, it’s not an easy task. But Yeomans makes the crucial point: it’s not the space rocks we know about that pose the biggest threat, but rather the thousands and thousands of large near-Earth asteroids we don’t know about that are the greatest danger. It’s not like the movie Armageddon; it would take years to develop a space mission to deflect or destroy an incoming asteroid, so it’s crucial that we find and track them – as Yeomans says, before they find us.
Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects--its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One…
This book is about asteroid hunters, written by an asteroid hunter – and she clearly loves her work. Nugent is an assistant professor of computational physics and planetary science at Olin College and worked on NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), which discovered hundreds of Potential Hazardous Objects – asteroids and comets – that could someday threaten Earth. You don’t have to be a scientist to enjoy this book. Nugent patiently walks us through the process of finding and tracking potentially dangerous space rocks with skill and passion for her subject.
Dr Carrie Nugent is an asteroid hunter - one of the select group of scientists working diligently to map our cosmic neighbourhood. For the first time ever we are reaching the point where we may be able to prevent a natural disaster resulting from an asteroid collision. Nugent will delve into the impact asteroids have had in the past: the extinction of the dinosaurs, the earth-sized hole Shoemaker-Levy 9 left in Jupiter just a few years ago, how the surprise hit on Chelyabinsk in Russia could have started a war and unlucky Ms Anne Hodges - the only person (that…
This book is an entertaining look at the history of mankind’s knowledge about asteroids, which began in 1801 with the discovery of the 600-mile wide asteroid Ceres. Today more than half a million asteroids in our Solar System have been identified, while billions more (mostly small ones) are still waiting to be discovered. The vast majority pose no threat to Earth, but they are fascinating anyway. There are asteroids shaped like giant dog bones, asteroids that resemble human skulls, asteroids that have smaller asteroids orbiting around them as they orbit around the sun. Peebles’ book tells you everything you need to know about these space rocks – and more things that you’ll want to know. A thoroughly enjoyable book.
Asteroids suggest images of a catastrophic impact with Earth, triggering infernos, tidal waves, famine, and death - but these scenarios have obscured the larger story of how asteroids have been discovered and studied. During the past two centuries, the quest for knowledge about asteroids has involved eminent scientists and amateur astronomers, patient research and sudden intuition, advanced technology and the simplest of telescopes, newspaper headlines and Cold War secrets. Today, researchers have named and identified the mineral composition of these objects. They range in size from 33 feet to 580 miles wide and most are found in a belt between…
This book is the story of the biggest collision of space objects mankind has ever seen – literally – told by the man who saw it coming. In 1993 Levy was working with astronomers Carolyn and Eugene Shoemaker at a mountain-top observatory in California when they spotted a comet that had been captured by Jupiter’s enormous gravity and sucked into orbit around the Solar System’s biggest planet. Levy and the Shoemakers predicted that pieces of the comet would soon strike Jupiter’s surface with almost unimaginable force – which prompted skepticism among some astronomers. But sure enough, in 1994 the comet fragments hit Jupiter’s surface with the collective force of a 50 million megaton bomb – thousands of times the energy of all the nuclear weapons on Earth. The event made us realize that if it could happen to Jupiter, it could happen to Earth – and that we’d better take the space rock threat seriously. It’s a dramatic story, and well told.
An account of the discovery of the Shoemaker-Levy 9 comet and its spectacular collision with Jupiter, just 6 months later, written by one of the comet's discoverers.
This book is about the positive side of Near-Earth Objects – that is, they can benefit mankind as well as threaten it. Lewis explains how asteroids are chock full of valuable minerals – iron, nickel, platinum, iridium, and so on – that are either rare or difficult and messy to extract on Earth. Lewis persuasively argues that it’s not just possible but almost inevitable that Earthlings will eventually start extracting those space rock riches -- not so much to bring them back to Earth but to use them for manufacturing industries in space, thus sparing our planet from much of the pollution that threatens our world. It’s not just futuristic day-dreaming; already private companies are spending big money to develop space-mining technologies. The bottom line of this fascinating book is that there’s gold in them thar hills – or rather, in them thar far reaches of space. And sooner than you think, we’ll be out there looking for it.
While we worry over the depletion of the earth's natural resources, the pollution of our planet, and the challenges presented by the earth's growing population, billions of dollars worth of metals, fuels, and life-sustaining substances await us in nearby space. In this visionary book, noted planetary scientist John S. Lewis explains how we can mine these precious metals from the asteroids, comets, and planets in our own solar system for use in space construction projects. And this is just one of the possibilities. Join John S. Lewis as he contemplates milking the moons of Mars for water and hollowing out…
The constellation we know as Taurus goes all the way back to cave paintings of aurochs at Lascaux. This book traces the story of the bull in the sky, a journey through the history of what has become known as the sacred bull.
Each of the sections is written from the perspective of the mythical Taurus, from the beginning at Lascaux to Mesopotamia, Ancient Egypt, and elsewhere. This is not just a history of the bull but also a view of ourselves through the eyes of the bull, illustrating our pre-literate use of myth, how the advent of writing and the urban revolution changed our view of ourselves, and how even bullfighting in Spain is a variation on the ancient sacrifice of the sacred bull.
The constellation we know as Taurus goes all the way back to cave paintings of aurochs at Lascaux. In I Am Taurus, author Stephen Palmer traces the story of the bull in the sky, starting from that point 19,000 years ago - a journey through the history of what has become known as the sacred bull. Each of the eleven sections is written from the perspective of the mythical Taurus, from the beginning at Lascaux to Mesopotamia, Ancient Egypt, Greece, Spain and elsewhere. This is not just a history of the bull but also an attempt to see ourselves through…
