A History Today Book of the Year

A world-renowned astronomer and an esteemed science writer make the provocative argument for space exploration without astronauts.

Human journeys into space fill us with wonder. But the thrill of space travel for astronauts comes at enormous expense and is fraught with peril. As our robot explorers grow more competent, governments and corporations must ask, does our desire to send astronauts to the Moon and Mars justify the cost and danger? Donald Goldsmith and Martin Rees believe that beyond low-Earth orbit, space exploration should proceed without humans.

In The End of Astronauts, Goldsmith and Rees weigh the benefits and risks of human exploration across the solar system. In space humans require air, food, and water, along with protection from potentially deadly radiation and high-energy particles, at a cost of more than ten times that of robotic exploration. Meanwhile, automated explorers have demonstrated the ability to investigate planetary surfaces efficiently and effectively, operating autonomously or under direction from Earth. Although Goldsmith and Rees are alert to the limits of artificial intelligence, they know that our robots steadily improve, while our bodies do not. Today a robot cannot equal a geologist’s expertise, but by the time we land a geologist on Mars, this advantage will diminish significantly.

Decades of research and experience, together with interviews with scientific authorities and former astronauts, offer convincing arguments that robots represent the future of space exploration. The End of Astronauts also examines how spacefaring AI might be regulated as corporations race to privatize the stars. We may eventually decide that humans belong in space despite the dangers and expense, but their paths will follow routes set by robots.

Lavishly illustrated volume revealing the intricacies of a 1742 map of the cosmos.
 
The expansive and intricate Atlas Coelestis, created by Johann Doppelmayr in 1742, set out to record everything known about astronomy at the time, covering constellations, planets, moons, comets, and more, all rendered in exquisite detail. Through stunning illustrations, historical notes, and scientific explanations, Phenomena contextualizes Doppelmayr’s atlas and creates a spectacular handbook to the heavens.
 
Phenomena begins by introducing Doppelmayr’s life and work, placing his extraordinary cosmic atlas in the context of discoveries made in the Renaissance and Enlightenment and highlighting the significance of its publication. This oversized book presents thirty beautifully illustrated and richly annotated plates, covering all the fundamentals of astronomy—from the dimensions of the solar system to the phases of the moon and the courses of comets. Each plate is accompanied by expert analysis from astronomer Giles Sparrow, who deftly presents Doppelmayr’s references and cosmological work to a modern audience. Each plate is carefully deconstructed, isolating key stars, planets, orbits, and moons for in-depth exploration. A conclusion reflects on the development of astronomy since the publication of the Atlas and traces the course of the science up to the present day. Following the conclusion is a timeline of key discoveries from ancient times onward along with short biographies of the key players in this history.  
 

It has already been called the scientific breakthrough of the century: the detection of gravitational waves. Einstein predicted these tiny ripples in the fabric of spacetime nearly a hundred years ago, but they were never perceived directly until now. Decades in the making, this momentous discovery has given scientists a new understanding of the cataclysmic events that shape the universe and a new confirmation of Einstein’s theory of general relativity. Ripples in Spacetime is an engaging account of the international effort to complete Einstein’s project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe’s structure and origin.

The quest for gravitational waves involved years of risky research and many personal and professional struggles that threatened to derail one of the world’s largest scientific endeavors. Govert Schilling takes readers to sites where these stories unfolded—including Japan’s KAGRA detector, Chile’s Atacama Cosmology Telescope, the South Pole’s BICEP detectors, and the United States’ LIGO labs. He explains the seeming impossibility of developing technologies sensitive enough to detect waves from two colliding black holes in the very distant universe, and describes the astounding precision of the LIGO detectors. Along the way Schilling clarifies concepts such as general relativity, neutron stars, and the big bang using language that readers with little scientific background can grasp.

Ripples in Spacetime provides a window into the next frontiers of astronomy, weaving far-reaching predictions and discoveries into a gripping story of human ambition and perseverance.

The detection of gravitational waves has already been called the scientific breakthrough of the century. Einstein predicted these tiny ripples in the fabric of spacetime over a hundred years ago, but they were only recently perceived directly for the first time. Ripples in Spacetime is an engaging account of the international effort to complete Einstein’s project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe’s structure and origin.

“Schilling’s deliciously nerdy grand tour takes us through compelling backstory, current research, and future expectations.”
—Nature

“A lively and readable account… Schilling underlines that this discovery is the opening of a new window on the universe, the beginning of a new branch of science.”
