How We See the Sky
A Naked-Eye Tour of Day and Night
Thomas Hockey
University of Chicago Press, 2002

Gazing up at the heavens from our backyards or a nearby field, most of us see an undifferentiated mess of stars—if, that is, we can see anything at all through the glow of light pollution. Today’s casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. Nowadays, we don’t need the sky, which is good, because we’ve made it far less accessible, hiding it behind the skyscrapers and the excessive artificial light of our cities. 

How We See the Sky gives us back our knowledge of the sky, offering a fascinating overview of what can be seen there without the aid of a telescope. Thomas Hockey begins by scanning the horizon, explaining how the visible universe rotates through this horizon as night turns to day and season to season. Subsequent chapters explore the sun’s and moon’s respective motions through the celestial globe, as well as the appearance of solstices, eclipses, and planets, and how these are accounted for in different kinds of calendars. In every chapter, Hockey introduces the common vocabulary of today’s astronomers, uses examples past and present to explain them, and provides conceptual tools to help newcomers understand the topics he discusses.


Packed with illustrations and enlivened by historical anecdotes and literary references, How We See the Sky reacquaints us with the wonders to be found in our own backyards.

Jupiter
William Sheehan and Thomas Hockey
Reaktion Books, 2018
Now in paperback, an accessible and engaging introduction to planetary science that will deepen our knowledge both of this magnificent planet and of our own place in the solar system.

Majestic and untwinkling, Jupiter is the grandest of all planets. It is the largest planet in our solar system and among the brightest objects in the night sky. It shines with a noble, steady luster, and its calming presence has inspired humans for centuries. Jupiter was the “beloved star” of the first serious observers of the planets, the ancient Sumerians and Babylonians, and has inspired poetic utterances from eminent writers such as William Wordsworth and Walt Whitman. It also continues to inspire contemporary astronomers and stargazers, and this beautifully illustrated volume brings our understanding of Jupiter right up to date.

The scientific study of Jupiter is at a watershed: NASA’s Juno space probe has entered orbit about Jupiter to investigate the planet, while information gleaned from improved telescopes and other robotic explorers in space continues to improve our understanding of the planet’s origin, evolution, and composition. Jupiter provides a concise and expert overview of the history of our observations of this largest of planetary spheres, as well as reports on the much-anticipated initial findings from the Juno space probe.
