Shoemaker by Levy
It was a lucky twist of fate when in the early1980s David Levy, a writer and amateur astronomer, joined up with the famous scientist Eugene Shoemaker and his wife, Carolyn, to search for comets from an observation post on Palomar Mountain in Southern California. Their collaboration would lead to the 1993 discovery of the most remarkable comet ever recorded, Shoemaker-Levy 9, with its several nuclei, five tails, and two sheets of debris spread out in its orbit plane. A year later, Levy would be by the Shoemakers' side again when their comet ended its four-billion-year-long journey through the solar system and collided with Jupiter in the most stunning astronomical display of the century.

Hidden History of Rockland & St. George
Down East Maine is well known for its breathtaking scenery and art museums. However, much of the history in the traditional mining and fishing area of Rockland and St. George remains untold. Hanson Gregory from Clam Cove invented the donut. Mary Brown Patten sailed a clipper around Cape Horn. Captain Albert Keller was shipwrecked on Easter Island and Effie Canning of Rockland composed the lullaby Rock a Bye Baby. Captain Charles Holbrook of Tenants Harbor and his ship, the Hattie Dunn, fell victim to a German U-boat in the Atlantic. Local author Jane Merrill uncovers the forgotten stories and personalities that bring this unique area's history into focus.
Theaters of Time and Space
Every year, millions of Americans visit planetariums and are captivated by their strikingly realistic portrayal of the night sky. Today, it is indeed difficult to imagine astronomy education without these magnificent celestial theaters. But projection planetariums, first developed in Germany, have been a part of American museum pedagogy only since the early twentieth century and were not widespread until the 1960s. In this unique social history, former planetarium director and historian of science Jordan D. Marché II offers the first complete account of the community of individuals and institutions that, during the period between 1930 and 1970, made planetariums the popular teaching aids th...
The Greatest Show in the Arctic
In Gilded Age America, Arctic explorers were fabulous celebrities—assured of riches and near-immortality so long as they reached the North Pole first. Of the many attempts to meet that goal, three American expeditions, launched from the Russian archipelago of Franz Josef Land, ended in abject failure, their exploits consigned to near-oblivion. Even so, these ventures—the Wellman expedition (1898–99), the Baldwin-Ziegler (1901–2), and the Fiala-Ziegler (1903–5)—have much to tell us about the personalities, politics, and economics of exploration in their day. In The Greatest Show in the Arctic, the first book to chronicle all three expeditions, P. J. Capelotti explores what went ri...
