Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon.

For as long as humans have lived, we have lived beneath the stars. But under the glow of today’s artificial lighting, we have lost the intimacy our ancestors once shared with the cosmos. In Starborn, cosmologist Roberto Trotta reveals how stargazing has shaped the course of human civilization. The stars have served as our timekeepers, our navigators, our muses—they were once even our gods. How radically different would we be, Trotta also asks, if our ancestors had looked up to the night sky and seen… nothing?

Written in simple and accessible language, this nontechnical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative.

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard’s Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth.
