Details the science behind the Copernican Revolution, the transition from the Earth-centered cosmos to a modern understanding of planetary orbits.

An astrophysicist recounts how her team of researchers surfed the cosmos to map our local universe—and discovered the Laniakea supercluster, home of the Milky Way. You are here: on Earth, which is part of the solar system, which is in the Milky Way galaxy, which itself is within the extragalactic supercluster Laniakea. And how can we pinpoint our location so precisely? For 20 years, astrophysicist Hélène Courtois surfed the cosmos with international teams of researchers, working to map our local universe. In this book, Courtois describes this quest and the discovery of our home supercluster. Courtois explains that Laniakea (which means “immense heaven” in Hawaiian) is the largest galaxy structure known to which we belong; it is huge, almost too large to comprehend—about 500 million light-years in diameter. It contains about 100,000 large galaxies like our own, and a million smaller ones. Writing accessibly for nonspecialists, Courtois describes the visualization and analysis that allowed her team to map such large structures of the universe. She highlights the work of individual researchers, including portraits of several exceptional women astrophysicists—presenting another side of astronomy. Key ideas are highlighted in text insets; illustrations accompany the main text. The French edition of this book was named the Best Astronomy Book of 2017 by the astronomy magazine Ciel et espace. For this MIT Press English-language edition, Courtois has added descriptions of discoveries made after Laniakea: the cosmic velocity web and the Dipole and Cold Spot repellers. An engaging account of one of the most important discoveries in astrophysics in recent years, her story is a tribute to teamwork and international collaboration.

Finding our Place in the Solar System gives a detailed account of how the Earth was displaced from its traditional position at the center of the universe to be recognized as one of several planets orbiting the Sun under the influence of a universal gravitational force. The transition from the ancient geocentric worldview to a modern understanding of planetary motion, often called the Copernican Revolution, is one of the great intellectual achievements of humankind. This book provides a deep yet accessible explanation of the scientific disputes over our place in the solar system and the work of the great scientists who helped settle them. Readers will come away knowing not just that the Earth orbits the Sun, but why we believe that it does so. The Copernican Revolution also provides an excellent case study of what science is and how it works.

The Scientific Revolution began with the publication of Copernicus’ heliocentric theory describing the Sun as the center of our solar system and all the known Universe. That revolutionary idea began a rethinking of our place in the Universe and no longer were the affairs of humanity considered as the centerpiece of all that was known. In the past century, with the advent of the theories of Special and General Relativity, the Copenhagen interpretation of quantum theory, and a more sophisticated conception of living system dynamics, there has been a new understanding of the central role of the observer or experiencer in the determination of natural phenomena and the actualization of reality. Modern advancements in information theory, semiotics, and consciousness studies have also led to a better comprehension of the relationship between 1st person and 3rd person perspectives and the limits of the Scientific Method. Science and religion have always had the common goal of trying to further our understanding of the world and its meaning for us. This book explores a possible return of science to a role as natural philosophy and a pathway to better understanding our place in the Universe.

Earth is just one of eight planets in our solar system. Readers can explore the sun, the planets, and what lies beyond Neptune in this nonfiction early reader.

Integrating astrology, mythology and spirituality, this book is a reflection on the themes of the astrological ages across the past 13,000 years and is an exploration of what astrology has to tell us about the meaning of the changes happening globally and culturally in this time. We are currently on the cusp of the Age of Aquarius, at the end of a 26,000 year precessional cycle and, according to ancient prophecies, at the close of a world era. With the recent discovery of the planetoids Sedna and Eris, new forms of consciousness are entering our awareness. Through listening to the messages of the stars and planets, we find guidance for our lives in this intense time of change. We live in a sentient universe, which is calling us back into relationship with the cosmos and with the Earth. In remembering our source (the galactic center), reconnecting with the spirit in all of life and in becoming centered within ourselves, we gain meaning and wisdom for who we are and who we are becoming and find a path for the healing and evolution of ourselves and our Earth.

What do scientists know about the possibility of life outside our solar system? How does Catholic science fiction imagine such worlds? What are the implications for Catholic thought? This collection brings together leading scientists, philosophers, theologians, and science fiction authors in the Catholic tradition to examine these issues. In the first section, Christian scientists detail the latest scientific findings regarding the possibility of life on exoplanets. The second part brings together leading Catholic science fiction authors who describe how “alien” life forms have been prevalent in the Catholic imagination from the Middle Ages right up to the present day. In the final section, Catholic philosophers and theologians examine the implications of discovering intelligent life elsewhere in the universe. Rather than worrying that the discovery of intelligent extraterrestrials might threaten the dignity of humans or their existence, the contributors here maintain that such creatures should be welcomed as fellow creatures of God and potential subjects of divine salvation.
