The supernova of 1604 marks a major turning point in the cosmological crisis of the sixteenth and seventeenth centuries. Capturing the eyes and imagination of Europe, it ignited an explosion of ideas that forever changed the face of science. Variously interpreted as a comet or star, the new luminary brought together a broad network of scholars who debated the nature of the novelty and its origins in the universe. At the heart of the interdisciplinary discourse was Johannes Kepler, whose book On the New Star (1606) assessed the many disputes of the day. Beginning with several studies about Kepler's book, the authors of the present volume explore the place of Kepler and the 'new star' in early modern culture and religion, and how contemporary debate shaped the course of science down to the present day. Contributors are: (1) Dario Tessicini, (2) Christopher M. Graney, (3) Javier Luna, (4) Patrick J. Boner, (5) Jonathan Regier, (6) Aviva Rothman, (7) Miguel A. Granada, (8) Pietro Daniel Omodeo, (9) Matteo Cosci, and (10) William P. Blair.

Mathematical Disquisitions: The Booklet of Theses Immortalized by Galileo offers a new English translation of the 1614 Disquisitiones Mathematicae, which Johann Georg Locher wrote under the guidance of the German Jesuit astronomer Christoph Scheiner. The booklet, an anti-Copernican astronomical work, is of interest in large part because Galileo Galilei, who came into conflict with Scheiner over the discovery of sunspots, devoted numerous pages within his famous 1632 Dialogue Concerning the Two Chief World Systems-Ptolemaic and Copernican to ridiculing Disquisitiones. The brief text (the original was approximately one hundred pages) is heavily illustrated with dozens of original figures, making it an accessible example of "geocentric astronomy in the wake of the telescope."

Setting Aside All Authority is an important account and analysis of seventeenth-century scientific arguments against the Copernican system. Christopher M. Graney challenges the long-standing ideas that opponents of the heliocentric ideas of Copernicus and Galileo were primarily motivated by religion or devotion to an outdated intellectual tradition, and that they were in continual retreat in the face of telescopic discoveries. Graney calls on newly translated works by anti-Copernican writers of the time to demonstrate that science, not religion, played an important, and arguably predominant, role in the opposition to the Copernican system. Anti-Copernicans, building on the work of the Danish astronomer Tycho Brahe, were in fact able to build an increasingly strong scientific case against the heliocentric system at least through the middle of the seventeenth century, several decades after the advent of the telescope. The scientific case reached its apogee, Graney argues, in the 1651 New Almagest of the Italian Jesuit astronomer Giovanni Battista Riccioli, who used detailed telescopic observations of stars to construct a powerful scientific argument against Copernicus. Setting Aside All Authority includes the first English translation of Monsignor Francesco Ingoli’s essay to Galileo (disputing the Copernican system on the eve of the Inquisition’s condemnation of it in 1616) and excerpts from Riccioli's reports regarding his experiments with falling bodies.
