“How do alien, faraway worlds reveal their existence to Earthlings? Let Donald Goldsmith count the ways. As an experienced astronomer and a gifted storyteller, he is the perfect person to chronicle the ongoing hunt for planets of other stars.” —Dava Sobel

Astronomers have recently discovered thousands of planets that orbit stars throughout our Milky Way galaxy. With his characteristic wit and style, Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that Earthlings with little background in astronomy or astrophysics can understand and enjoy.

Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds, which bear little resemblance to the planets in our solar system. The sizes, masses, and orbits of exoplanets detected so far raise new questions about how planets form and evolve. Still more tantalizing are the efforts to determine which exoplanets might support life. Astronomers are steadily improving their means of examining these planets’ atmospheres and surfaces, with the help of advanced spacecraft sent into orbits a million miles from Earth. These instruments will provide better observations of planetary systems in orbit around the dim red stars that throng the Milky Way. Previously spurned as too faint to support life, these cool stars turn out to possess myriad planets nestled close enough to maintain Earthlike temperatures.

The quest to find other worlds brims with possibility. Exoplanets shows how astronomers have broadened our planetary horizons, and suggests what may come next, including the ultimate discovery: life beyond our home planet.

In the 1870s, approximately 18,000 Mennonites migrated from the southern steppes of Imperial Russia (present-day Ukraine) to the North American grasslands. They brought with them an array of cultural and institutional features that indicated they were a "transplanted" people. What is less frequently noted, however, is that they created in their everyday lives a world that ensured their cultural longevity and social cohesiveness in a new land.Their adaptation to the New World required new concepts of social boundary and community, new strategies of land ownership and legacy, new associations, and new ways of interacting with markets. In Hidden Worlds, historian Royden Loewen illuminates some of these adaptations, which have been largely overshadowed by an emphasis on institutional history, or whose sources have only recently been revealed. Through an analysis of diaries, wills, newspaper articles, census and tax records, and other literature, an examination of inheritance practices, household dynamics, and gender relations, and a comparison of several Mennonite communities in the United States and Canada, Loewen uncovers the multi-dimensional and highly resourceful character of the 1870s migrants.
