With over 150,000 copies sold since its first publication, this is one of the most popular astronomy books of all time. This unique guidebook to the night sky shows you how to observe a host of celestial wonders. Its distinct format of object-by-object spreads illustrates how deep-sky objects and planets actually look through a small telescope, while its large pages and spiral binding allow for use outside. Along with updated star names and astronomical information, this new edition provides links to a dedicated webpage with up-to-date tables and images, and an improved planets chapter. The many Dobsonian-friendly images and small telescope views have been revised to account for changes in modern telescope technology, such as larger field of view eyepieces. With dedicated chapters on Northern and Southern Hemisphere objects, it's never been easier to explore the night sky, wherever you are.

Angelo Secchi was a key figure in 19th century science. An Italian Jesuit and scientist, he helped lead the transition from astronomy to astrophysics and left a lasting legacy in the field. Secchi’s spectral classification of stars was a milestone that paved the way for modern astronomical research. He was also a founder of modern meteorology and an innovator in the design and development of new instruments and methods across disciplines.This contributed volume collects together reviews from an international group of historians, scientists and scholars representing the multiple disciplines where Secchi made significant contributions during his remarkable career. It analyzes both his famous and lesser known pioneering efforts with equal vigor, providing a well-rounded narrative of his life’s work. Beyond his scientific and technological work, his role as a Jesuit priest in Rome during the turbulent years of the mid 19th century is also described and placed in the context of his scientific and civic activities.

How does a scientist find God in the universe? My Theology: Finding God in the Universe is the personal reflection of a Jesuit brother and astronomer, the director of the Vatican Observatory. Br. Guy Consolmagno SJ insists that science is more than observing the universe; it’s learning how to pay attention, how to concentrate on one aspect while setting aside, at least momentarily, all the other interesting aspects that can distract us from a deeper knowledge of the universe…. or of God. In his telling, Joy is our compass, Truth is our goal; and Imagination weaves the story where we situate the joy that leads us to truth. Most importantly, both science and theology are done within a community of fellow seekers, where we share the stories that teach us how to explore, and with whom we can try to make sense of what we think we have found.

“[A] brilliant defense of science’s place in the religious life (and vice versa).”—Publisher’s Weekly


Jesuit Brother Guy Consolmagno’s moving and intellectually playful memoir of a life lived in the active interplay of science and religion is now available in a handsome paperback edition.


Blending memoir, science, history, and theology, Consolmagno takes us on a grand adventure. We revisit the infamous “Galileo affair” and see that it didn’t unfold in quite the way we thought. We get a rare glimpse into the world of working scientists and see how scientific discoveries are proposed and advanced. We learn the inside story of the “Mars meteorite”: how can we be sure it’s really from Mars, and why can’t scientists agree on whether or not it contains evidence of life? Brother Astronomer memorably sets forth one scientist’s conviction that the universe may be worth studying only if it is the work of a Creator God.

Laudato Si’ insists on a revolutionary human response to the public challenges of our time concerning the ecological crisis. The volume takes up the revolutionary spirit of Pope Francis and speaks to the economic, technological, political, educational, and religious changes needed to overcome the fragile relationships between humans and Earth. This volume identifies various systemic factors that have produced the anthropogenic ecological crisis that threatens the planet and uses the ethical vision of Laudato Si’ to promote practical responses that foster fundamental changes in humanity’s relationships with Earth and each other. The essays address not only the immediate behavioral changes needed in individual human lives, but also the deeper, societal changes required if human communities are to live sustainable lives within Earth’s integral ecology. Thus, this volume intentionally focuses on a plurality of cultural contexts and proposes solutions to problems encountered in a variety of global contexts. Accordingly, the contributors to this volume are scholars from a breadth of interdisciplinary and cultural backgrounds, each exploring an ethical theme from the encyclical and proposing systemic changes to address deeply entrenched injustices. Collectively, their essays examine the social, political, economic, gender, scientific, technological, educational, and spiritual challenges of our time as these relate to the ecological crisis.
