Cosmic Bullets: How Asteroids and Comets Ended the Dinosaurs, Built Our Oceans, and Could Destroy Civilization Tomorrow
by Astrid Blackwood
A riveting exploration of the celestial forces that have shaped-and may yet unmake-life on Earth.
Cosmic Bullets takes readers on a journey through deep time and cosmic peril, uncovering how asteroids and comets have left an indelible mark on our planet's history. From the Chicxulub impact that wiped out the dinosaurs to the icy bodies that may have seeded our oceans, Astrid Blackwood weaves together cutting-edge science and compelling narrative to reveal the dual nature of these spacefaring objects-as creators and destroyers.
With chapters covering past extinction events, the role of cosmic impacts in shaping Earth's climate and geology, and the urgent global efforts to detect and deflect potential threats, Cosmic Bullets offers a sobering and fascinating look at our planet's vulnerability. Featuring insights into current planetary defense systems and space missions, this book is essential reading for anyone curious about Earth's past, our place in the cosmos, and the future that hangs in the balance.
