Seeking the Face of God: The Lives and Discoveries of Catholic Scientists

Audio series 3 hours Level: all audiences This is a series of conversations between Dr. Guy Consolmagno, S. J., Director of the Vatican Observatory, and Dr. Michelle Francl-Donnay, professor of chemistry and the chair of the chemistry department at Bryn Mawr College, and an adjunct scholar of the Vatican Observatory. The interviews are published by Now You Know Media. From the web site of Now You Know: In Seeking the Face of God, two leading scientists from the Vatican Observatory debate what it means to be a practicing Catholic and a professional scientist. Tracing back across 1,000 years of history, you’ll reflect on the role of faith in science…. Beginning with a brief overview of the history of science, Consolmagno and Francl-Donnay highlight Catholic contributions to medicine, mathematics, computer science, astronomy, and chemistry before arriving at the question of our place in the cosmos. While some, like Gregor Mendel, are famous for their discoveries, Consolmagno and Francl-Donnay introduce you to … Continue reading →

The Pope and the Comet

Article 4 pages Level: all audiences This brief article (published in 1908 in Popular Astronomy) by Fr. William F. Rigge, S. J., an astronomer at Creighton University, debunks the story that Pope Callixtus III invoked his papal authority against Halley’s comet. Rigge writes that “it seems that no article can be written on Halley’s comet without bringing in the oft-told story of the bull which Pope Callixtus III so ineffectually launched against it….” Rigge cites several pieces of evidence against this story, the strongest being that not that many documents were produced during the short papacy of Callixtus III, and Fr. Rigge was able to read them all. “It was an easy task for me to read all the documents of this pope,” he writes, “and I can attest from my own personal knowledge that not only is there no bull against or concerning a comet, there is not even a paragraph, nor a phrase, nor a word, which might be … Continue reading →

On Stellar Spectrometry

Article 4 pages Level: high school and above This is an 1868 paper by Fr. Angelo Secchi, who conducted pioneering research into the nature of stars and whose work laid the foundations for the modern Vatican Observatory. Here Fr. Secchi groups stars by the characteristics of their spectra, noting that stars seem to fall into a certain number of types. He writes, “We have therefore, without doubt, in the heavens a grand fact, the fundamental distinction between the stars according to a small number of types; this opens a field for very many important cosmological speculations.” He also notes that observing the spectra of stars can tell us something about their motions. Indeed, studying the motions of stars by means of their spectra has yielded all sorts of information about them, including whether they have planets orbiting them. Fr. Secchi’s paper was published in the Report of the Thirty-Eighth Meeting of the British Association for the Advancement of Science [1868]. Click … Continue reading →

Finding God in the Cosmos: An Interview with a Vatican Astronomer

Article 1700 words Level: all audiences A 2018 interview of Vatican Observatory astronomer David Brown, S.J., by Sean Salai, S.J., for America: The Jesuit Review. Salai writes: David Brown, S.J., is a Vatican astronomer specializing in stellar evolution and a native of New Orleans who joined the Society of Jesus in 1991 after earning his B.S. in physics at Texas A&M University. Ordained a priest in 2002, Father Brown completed his Ph.D. in astrophysics at the University of Oxford in England in 2008. Father Brown joined the Vatican Observatory in November 2008, working as a research astronomer and serving as caretaker of the telescopes in Castel Gandolfo. He is a member since 2009 of the American Astronomical Society and since 2012 of the International Astronomical Union. On Oct. 2, I interviewed him at Rockhurst High School during a lecture stop in Kansas City. The focus of the interview is the overlap between Fr. Brown’s vocation as a Jesuit and his … Continue reading →

God Is Also a Cosmologist

Article 900 words Level: all audiences This New York Times article is about an international gathering of cosmologists and astrophysicists hosted by the Center for Theology and the Natural Sciences, in Berkeley, California in 1997. The purpose of the conference was to explore how contemporary cosmology, the scientific study of the universe, might be compatible with various religions, with focus on the three monotheistic faiths: Judaism, Christianity and Islam. Featured in the article are Joel Primack, a cosmologist at the University of California at Santa Cruz; Andrei Linde, a Stanford University physicist; John Barrow, from Sussex University; Edward Harrison, an astrophysicist with the University of Massachusetts; and Fr. William Stoeger, S.J., of the Vatican Observatory Research Group at the University of Arizona at Tucson. Click here to access this article courtesy of The New York Times. … Continue reading →

The Church opposed to Science

Article (book chapter) 11 pages Level: high school and above This is a chapter from an 1895 book entitled Plain Facts for Fair Minds: An Appeal to Candor and Common Sense, by George M. Searle, “Priest of the Congregation of St. Paul the Apostle; Professor of Mathematics and Astronomy in the Catholic University of America and Director of the Observatory”. George Searle was an astronomer with the Harvard Observatory who converted to Catholicism, entered the priesthood, and then continued his scientific work at the Catholic University of America. Fr. Searle was eventually elected superior-general of the Paulists, serving from 1904 to 1910. Plain Facts was written for a non-Catholic audience, in a time when the status of Catholics and the Catholic church in the USA was different from today. Fr. Searle states in the introduction to Plain Facts that the book is— addressed principally to what are commonly called Bible Christians, who form the majority of our Protestant population, in order to … Continue reading →

The International Astronomical Union (IAU) and the Hubble–Lemaître law

Article (2) 1900 words (total) Level: all audiences In October 2018 the International Astronomical Union voted overwhelmingly to change the name of the “Hubble law” (relating distance and velocity in the universe’s expansion) to the “Hubble–Lemaître law”, thus including the name of Fr. Georges Lemaître in the law. These are two articles from the prominent journals Science and Nature discussing the IAU vote. Click here for an article on the vote from Nature.

Who Discovered the Expanding Universe

Article 22 pages Level: university Historians of science Helge Kragh and Robert W. Smith provide an overview of the discovery of the expanding universe and who might be credited with making that discovery. They argue that, while Edwin Hubble is generally credited with the discovery of the expansion of the universe, and while a number of different scientists did in fact contribute to the discovery in significant ways, in fact Fr. Georges Lemaître discovered the expansion of the universe, insofar as he gave theoretical and observational reasons for it. (Lemaître would go on to become a member of the Pontifical Academy of Sciences in 1936, and to serve as its president from 1960 until his death in 1966). Hubble, meanwhile was ambivilant towards the whole concept of an expanding universe. Kragh and Smith also discuss why Hubble is credited with the discovery. They trace the history of how Hubble’s role in the discovery was elevated, “at the expense of everyone … Continue reading →
