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.
An hourly guide that tracks twenty-four stars, stellar clusters, and constellations across the sky to reveal their luminous lives and lore.
Over the course of a day, the constellations slowly shift, rising in the east and setting in the west, all due to the Earth’s rotation. A full turn of the celestial sphere, that bowl above us where the stars seemingly appear fixed to the surface, is completed once every twenty-four hours. In fact, the stars first defined the twenty-four-hour day, and one star, our sun, rules the circadian rhythms of all life on our planet. This short book sweeps through the celestial sphere hour by hour, introducing a remarkable cast of stellar characters with each chapter. Celebrated science writer Marcia Bartusiak and mathematician Stephen Lowe blend practical astronomy with fascinating history to share unique cosmological stories.
This husband and wife team explain that observers have long split the sky into twenty-four hours of “right ascension”—a celestial equivalent of longitude and a universal scheme for locating cosmological objects. Each chapter of Star Day presents a single right ascension hour, from the stellar death of Supernova 1885A (0th Hour)—an explosion that helped reveal the size of the universe—to Scheat (23rd Hour), an aging red giant. Twice the mass of the Sun and some 1,500 times as bright, Scheat sometimes guides amateur astronomers to distant galaxies. In between, we learn about humans’ pole star, Polaris (2nd hour), and meet the supermassive black hole at the center of our Milky Way galaxy (17th hour). By the end of our star day, we will appreciate both our own stellar origins and the fragile and deep connections between human civilizations and the ever-changing heavens. Star Day reminds us that wonder and discovery are easily available, all for the simple price of looking up.
For each chapter, artist Matthew Green has depicted these stellar scenes with entrancing pen-and-ink drawings. Working together to narrate and illustrate these stars, Bartusiak, Lowe, and Green have created an engaging read that is a perfect way to spend an hour or two—and a true gift to both seasoned skywatchers and curious beginners.
Engineer and bubble scientist Lucy Rogers invites us to explore the wonders of the air, sky, and space; understand the science; and appreciate the insights this offers about life on Earth. The sky is a world of endless wonder. From the intricate dance of clouds and the vibrant hues of the aurora borealis to the marvel of effortless soaring birds and the silent majesty of the stars, it is a living storybook. Join Rogers on a marvelous adventure through a kite market in India, creep through the Borneo jungle to witness millions of bats pour out of a cave at dusk, venture to Tornado Alley to chase the raw power of storms, and journey to Mexico to stand in awe of a total solar eclipse. Up is for anyone who has ever looked up at the sky in awe and needs to know the science behind its never-ending phenomena.
