Book Description
The unfinished sci-fi masterpiece by the author of Stranger in a Strange Land—completed by the Hugo Award–winning author of The Stardance Trilogy. Joel Johnston has found the love of his life in Jinny Hamilton. Life would be perfect if only he earned enough money to support a family. But now that Jinny knows his love is true, she reveals an incredible secret: she is really Jinny Conrad, granddaughter of Richard Conrad, the wealthiest man in the solar system. And now that Joel proven his love for Jinny, her family has a plan for him. Joel is to be groomed for a place in the vast Conrad empire and sire a dynasty to carry on the family business. Most men would jump at the opportunity. But to Jinny’s surprise, and even his own, Joel turns down her generous offer and sets off on the mother of all benders. When he wakes up on a colony ship heading into space, he decides it’s time to forget Jinny and make a life among the stars. But his plans—and the plans of billions of others—are shattered by a cosmic cataclysm so devastating it will take all of humanity’s strength and ingenuity just to survive. When an outline for Variable Star was found among Robert A. Heinlein’s papers, Spider Robinson was commissioned to complete the novel. The result is a thrilling new work of science fiction from two of the genre’s greatest minds.

Book Description
"A short, excellent account of [Leavitt’s] extraordinary life and achievements." —Simon Singh, New York Times Book Review George Johnson brings to life Henrietta Swan Leavitt, who found the key to the vastness of the universe—in the form of a “yardstick” suitable for measuring it. Unknown in our day, Leavitt was no more recognized in her own: despite her enormous achievement, she was employed by the Harvard Observatory as a mere number-cruncher, at a wage not dissimilar from that of workers in the nearby textile mills. Miss Leavitt’s Stars uncovers her neglected history.

Book Description
From #1 New York Times bestselling author Dava Sobel, the "inspiring" (People), little-known true story of women's landmark contributions to astronomy A New York Times Book Review Notable Book of 2017 Named one of the best books of the year by NPR, The Economist, Smithsonian, Nature, and NPR's Science Friday Nominated for the PEN/E.O. Wilson Literary Science Writing Award "A joy to read.” —The Wall Street Journal In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or “human computers,” to interpret the observations their male counterparts made via telescope each night. At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges—Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates. The “glass universe” of half a million plates that Harvard amassed over the ensuing decades—through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography—enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard—and Harvard’s first female department chair. Elegantly written and enriched by excerpts from letters, diaries, and memoirs, The Glass Universe is the hidden history of the women whose contributions to the burgeoning field of astronomy forever changed our understanding of the stars and our place in the universe.

Book Description
Making Stars Physical offers the first extensive look at the astronomical career of John Herschel, son of William Herschel and one of the leading scientific figures in Britain throughout much of the nineteenth century. Herschel’s astronomical career is usually relegated to a continuation of his father, William’s, sweeps for nebulae. However, as Stephen Case argues, John Herschel was pivotal in establishing the sidereal revolution his father had begun: a shift of attention from the planetary system to the study of nebulous regions in the heavens and speculations on the nature of the Milky Way and the sun’s position within it. Through John Herschel’s astronomical career—in particular his work on constellation reform, double stars, and variable stars—the study of stellar objects became part of mainstream astronomy. He leveraged his mathematical expertise and his position within the scientific community to make sidereal astronomy accessible even to casual observers, allowing amateurs to make useful observations that could contribute to theories on the nature of stars. With this book, Case shows how Herschel’s work made the stars physical and laid the foundations for modern astrophysics.

Book Description
An accessible, informative guide to identifying constellations and other incredible features of the sky, whether you’re hiking, camping, or stargazing from your backyard. Discover the Stars leads you on a tour of all the stars and constellations visible with the naked eye and introduces you to deep-sky objects that can be seen with binoculars or a simple telescope. The tour is conducted by the editor of Astronomy magazine, Richard Berry, whose two-color, computer-plotted sky maps and clear instructions make stargazing fun and productive from your first night out. The heart of Discover the Stars is two sections of big, beautiful sky maps and charts. The first section features twelve maps that show the entire sky overhead as it appears during each month of the year. These outline all the constellations visible anywhere in the Northern Hemisphere, and the accompanying text reveals the rich ancient mythology that surrounds the star groups. The second section is made up of twenty-three star charts that depict smaller regions of the sky in great detail. These charts give the names of key stars and lead you to fascinating features such as stars with unusual colors, double stars, variable stars, nebulae, and galaxies. Separate chapters cover basics, such as how the stars move through the sky, how to find your way around the moon and the planets, making an astronomer's flashlight, and choosing and using a telescope—all in terms that are easy to grasp and remember. Discover the Stars is the perfect introduction to the heavens, simple enough to be useful if you're just starting out but packed with enough information to keep you learning and enjoying the stars for years to come.
