Could a giant asteroid or comet crash into Earth and annihilate life as we know it? Many astronomers, once skeptical of such risks, now recognize the serious danger. In this exploration, Duncan Steel, a leading expert and director of a global asteroid and comet search program, delves into chilling scientific findings. He narrates the compelling story of how detection efforts revealed a troubling history of impacts, including the comet likely responsible for the dinosaurs' extinction. Advances in telescope tracking have identified at least 2,000 objects orbiting Earth that could strike with nuclear force. Calculations indicate that Earth is bound to face another catastrophic collision eventually. Potential outcomes include towering ocean waves that could devastate coastal areas, massive fires, and clouds of dust blocking sunlight, crippling agriculture. Steel expertly assesses these threats and discusses proposed strategies for detecting and neutralizing incoming celestial bodies, including Edward Teller's controversial suggestion of using a nuclear bomb. This account vividly illustrates the existential threat from space and the scientific community's response. With an unprecedented opportunity to avert disaster, the book argues that failing to act would be both dangerous and unwise.
