We cannot find quick and easy answers for Frequently Asked Questions; if we could, people wouldn’t keep asking them. That means that they’re worth looking at simply as a way of understanding why maybe these aren’t exactly the questions we need to be asking.
A lot of questions that are frequently asked, are more general questions about God and the Universe than the specific topics covered elsewhere. A discussion of some of them can be found here.

Across the Universe: Christmas Presence
Article (blog post)- 700 words
- General audiences
Vatican observatory astronomer Br. Guy Consolmagno, S. J., writes (in a post for The Catholic Astronomer blog) about both the Book of Job and about how he finds doing science to be like playing a game with God :
What’s it like, I am sometimes asked, to be both a Jesuit brother and an astronomer? I can compare it most easily to another memory from my childhood. I can recall a rainy summer afternoon, in our cottage by Lake Huron, spent playing cards with my mother. I couldn’t have been more than nine or ten years old, and I have never been much of a card player, but that wasn’t the point. It was a way for her to spend time with me, a young boy who would squirm at any overt sign of affection, a way of showing me that I was loved….
So how is that like being a Jesuit scientist? Because I feel that same emotion, now, in the lab. Every corner of nature that I puzzle over, every data set I plot hoping to see a pattern jump out, is a little game set for me by the Creator. Every time I finally get the solution, I can feel him cheering me on, laughing and saying, “Great! Now here’s another one.” Science is the greatest game; a game I get to play with God. It’s his way of telling me he loves me. My mom taught me that. And in the background, the stars sing for joy.

Vatican Observatory Director Br. Guy Consolmagno, S. J. writes on The Catholic Astronomer blog about the 125th birthday of the Vatican Observatory, and the history that lead to its foundation by Pope Leo XIII. Reflecting on that history, Br. Consolmagno writes:
But our cosmological ideas moved from Copernicus’ fixed sun, through Kepler’s elliptical orbits, to Kant’s idea of galaxies as island universes and Herschel’s measurement of our place in the Milky Way. Our modern speculations about multiple universes carry as much a tinge of science fiction as of natural philosophy. One lesson I hope we’ve learned is that no modern cosmology is a good basis for theological doctrine, simply because no matter how well founded our astronomy is we can expect it will eventually go out of date.

Br. Guy Consolmagno, S. J., an astronomer with the Vatican Observatory, writes in a post on The Catholic Astronomer blog about using the Vatican Advanced Technology Telescope or VATT to study small bodies in the outer solar system:.
By how often they brighten and dim, we measure how fast these bodies spin; by how much their brightness changes during these cycles, we get a measure of their irregular shapes. It is not particularly thrilling work. We point the telescope at a given object; take a three-minute exposure with our electronic camera; and then another exposure; and another; and another… These objects typically take about eight hours or more per spin; so we observe one body per night as it rises, crosses the sky, and sets in the west… checking the images for clarity, tweaking the focus, watching the skies to make sure that clouds are not moving in….
Adventures of a Vatican Astronomer – Br. Guy Consolmagno SJ

- General Audience
Br. Guy Consolmagno, S. J., an astronomer at the Vatican Observatory, gave this talk at the SETI Institute on February 22, 2013
No scientist is a Spock-like android; a scientist’s work is as intuitive, and just as full of human foibles, as a painting, a symphony, or a prayer. But most of us don’t have the opportunity (or training) to reflect on the human dimensions of our work. Br. Guy Consolmagno does; he is both a Jesuit brother and a planetary scientist at the Vatican Observatory, splitting his time between the meteorite collection in Rome (which he curates) and the Vatican telescope in Arizona. Thanks to his Vatican connections, his work has sent him around the world several times to dozens of countries and every continent (including a meteorite hunting expedition to Antarctica). In this talk he will share some of those adventures, and reflect on the larger meaning of our common experience as scientists… not only what we do, but why we do it.

Deep-dish astronomy: First light for VATT
Observing is now under way at the new Mount Graham International Observatory in Arizona. At the end of January, Richard P. Boyle, S.J. (Vatican Observatory) and Austin B. Tomaney (Columbia University) took the first visible-light images with the 1.8-meter Vatican Advanced Technology Telescope (VATT). First among the $3-million instrument’s noteworthy attributes is its deep, “salad-bowl” f/1.0 primary mirror (S&T: March 1994, page 12). It was one of the first to be formed by spin-casting techniques developed at the University of Arizona. Such a fast primary requires the secondary to be positioned with micron precision to achieve proper focus. These inaugural images of the Crab Nebula in Taurus (top) and globular cluster M3 in Canes Venatici (bottom) are 300-second and 100-second exposures, respectively. Each has an 11-arcminute field of view. Vatican astronomers hope to achieve subarcsecond resolution by tilting the secondary mirror to compensate for atmospheric turbulence. Courtesy Richard P.

St. Thomas Aquinas – The Knowledge of the Creatures is Useful to Avoid Errors Concerning God
- Book excerpt
- 1400 words
- University level
In this Summa contra Gentiles discussion on created things (that is, on the creatures or the works of God), Thomas Aquinas comments on the value for Faith inherent in understanding these things. This excerpt has been selected by the Interdisciplinary Encyclopedia of Religion and Science (Inters.org), which is edited by the Advanced School for Interdisciplinary Research, operating at the Pontifical University of the Holy Cross, Rome, and directed by Giuseppe Tanzella-Nitti. St. Thomas gives a number of reasons for studying the works of God:
First, because meditation on His works enables us in some measure to admire and reflect upon His wisdom…. Secondly, this consideration [of God’s works] leads to admiration of God’s sublime power, and consequently inspires in men’s hearts reverence for God…. Thirdly, this consideration incites the souls of men to the love of God’s goodness…. Fourthly, this consideration endows men with a certain likeness to God’s perfection…. It is therefore evident that the consideration of creatures has its part to play in building the Christian faith. And for this reason it is said: “I will remember the works of the Lord, and I will declare the things I have seen: by the words of the Lord are His works” (Ecc 42:15)
St. Thomas also argues that knowledge of the the works of God serves to destroy errors concerning God:
First, because through ignorance of the nature of creatures men are sometimes so far perverted as to set up as the first cause and as God that which can only receive its being from something else…. Secondly, because they attribute to certain creatures that which belongs only to God…. Thirdly, because through ignorance of the creature’s nature something is subtracted from God’s power in its working upon creatures…. Fourthly, through ignorance of the nature of things, and, consequently, of his own place in the order of the universe, this rational creature, man, who by faith is led to God as his last end, believes that he is subject to other creatures [such as the stars] to which he is in fact superior…. It is, therefore, evident that the opinion is false of those who asserted that it made no difference to the truth of the faith what anyone holds about creatures, so long as one thinks rightly about God, as Augustine tells us in his book On the Origin of the Soul [IV, 4]. For error concerning creatures, by subjecting them to causes other than God, spills over into false opinion about God, and takes men’s minds away from Him, to whom faith seeks to lead them.

The Total Solar Eclipse of July 29th, 1878
Article- 13 pages
- High school level and above
This article by J. M. Degni, S. J. from the 1878 American Catholic Quarterly Review provides an interesting look at a scientific article in a nineteenth-century Catholic periodical. “The Total Solar Eclipse” follows articles on the position of the Blessed Virgin in Catholic theology, Sir Thomas More, Catholic poetry, and Pope Sixtus V, among others. It features significant discussion of topics in astronomy such as spectroscopy and the work of Fr. Angelo Secchi. It also features a table of numerical data on temperature and humidity during the eclipse, and a full-page sketch of the eclipse made by Fr. Benedict Sestini. This sketch is also on the cover of the magazine. Degni concludes, “Many minor details, revealed by the spectroscope, the polariscope, and other instruments of observation, we must omit for brevity’s sake…. we must patiently await the full examination and comparison of the various observations taken on the 29th before the truth can be reached on this and many other points open to discussion. Meanwhile, we confidently assert that the observations made on the late eclipse will be found to have materially augmented our knowledge regarding the central orb of the solar system.”

Religion and Science: Roman Catholicism
- Encyclopedia article

- High school level and above
An article entitle “Christianity, Roman Catholic, Issues in Science and Religion” in the Encyclopedia Of Science And Religion. This article was written by Fr. George V. Coyne, S. J. (Director of the Vatican Observatory from 1978 to 2006). Coyne writes:
The most distinctive features of Roman Catholicism that influence the religion-science dialogue are its hierarchical and authoritative structure and its emphasis upon the rational foundations for religious belief. Many of the divisions that have occurred within Christianity in the course of history have their origins in one or both of these characteristics of Roman Catholicism. The history of the interaction within Roman Catholicism between science and religion has been dominated by its hierarchical structure. On the other hand the insistence on reason as fundamental to the relationship of human beings to the universe and, therefore, to the creator of the universe has played an important role in the birth of modern science and provides a platform for the dialogue between the belief system of Roman Catholicism and other disciplines, especially science.

Jesuit Science

Br. Guy Consolmagno, S. J., an astronomer with the Vatican Observatory, discusses Jesuits and their many contributions to science in an article and in a talk (on video). Br. Consolmagno notes:
A Jesuit scientist, supported by the order, is often not tied to a three-year funding cycle or six-year tenure review. Thus we have the time – it may take decades – to catalogue double stars, seismic velocities, or patterns in climate or terrestrial magnetic fields. Jesuits, for instance, invented the basic taxonomy of the plants of India. But this sort of science often meant that their work was unappreciated by their immediate peers. Famously in the 19th century the Whig historian and politician Thomas Macaulay sneered that the Jesuits “appear to have discovered the precise point to which intellectual culture can be carried without risk of intellectual emancipation” and that being a Jesuit “has a tendency to suffocate, rather than to develop, original genius.”

Brother Guy Consolmagno is a Planetary Scientist at the Vatican Observatory. He is the curator of the Vatican meteorite collection, which is one of the largest in the world. He earned a degree from MIT and did post-doctorate work at MIT and the Harvard College Observatory. When he was 29, he joined the Peace Corps in Kenya. There, he taught suffering people about astronomy. He discovered that the desire for scientific knowledge is not limited to educated westerners, but is original and alive in the poor and uneducated. In this way, he discovered that astronomy belongs to us all. In 1992, he became a Jesuit Brother. In 2000, he was honored by the International Astronomical Union for his contributions to the study of meteorites and asteroids with the naming of “Asteroid 4597 Consolmagno”.

Telescopes: Through the Looking Glass
Book- 234 pages
- General audiences
This book by Marvin Bolt was published in 2009, the year of the 400th anniversary of Galileo’s use of the telescope. It provides a readable history of the telescope by way of highlighting items that are on exhibit in the “Telescopes: Through the Looking Glass” exhibit at the Adler Planetarium in Chicago. Scattered throughout this beautifully illustrated book can be found references to the works of various clerics, such as Bartholomaeus Anglicus (1203-1274), Ferdinand Verbiest (1623-1688), Francesco Bianchini (1662-1729), and others. Those planning a visit to the Adler might enjoy a look through this book in advance.
From the publisher, Adler Planetarium:
Through the Looking Glass celebrates the 400th anniversary of the telescope and the 2009 International Year of Astronomy. This exhibition catalogue focuses on ninety-nine artifacts from the Adler Planetarium’s world-class collection of historic telescopes. From the simple lenses of the world’s earliest telescopes 400 years ago to the complex computer-driven mirrors of current telescopes, these tools have gathered information about our nearest astronomical neighbors and the most distant objects in the universe. Through the Looking Glass examines this story through select rare books, works on paper, telescopes, and other instruments from the Adler Planetarium’s collection. Introductory paragraphs provide background information for each of four time periods, with each section featuring artifact entries that describe each object’s place in the fascinating history of the telescope. Telescope-makers intended for their work to be looked at as well as looked through. With this catalogue, readers can enjoy the craftsmanship of telescope-making over the centuries, and catch a glimpse of their importance and of the significant discoveries they enabled.

Galileo Goes to Jail and Other Myths about Science and Religion
- Book
- 320 pages
- High school level and above
This 2009 book, edited by Ronald Numbers, contains much that will be of interest to many readers. From the publisher, Harvard University Press:
If we want nonscientists and opinion-makers in the press, the lab, and the pulpit to take a fresh look at the relationship between science and religion, Ronald L. Numbers suggests that we must first dispense with the hoary myths that have masqueraded too long as historical truths. Until about the 1970s, the dominant narrative in the history of science had long been that of science triumphant, and science at war with religion. But a new generation of historians both of science and of the church began to examine episodes in the history of science and religion through the values and knowledge of the actors themselves. Now Ronald Numbers has recruited the leading scholars in this new history of science to puncture the myths, from Galileo’s incarceration to Darwin’s deathbed conversion to Einstein’s belief in a personal God who “didn’t play dice with the universe.” The picture of science and religion at each other’s throats persists in mainstream media and scholarly journals, but each chapter in Galileo Goes to Jail shows how much we have to gain by seeing beyond the myths.

The Day Without Yesterday: Lemaître, Einstein and the Birth of Modern Cosmology
Book- 262 pages
- University level
This 2005 book by John Farrell (published by Thunder’s Mouth Press/Avalon Publishing Group) provides an in-depth and at at times technical discussion of the life and work of Fr. Georges Lemaître, the Belgian priest who used the ideas of Albert Einstein to developed what is now known as the “Big Bang Theory”—the scientific idea that the universe had a beginning on a “day without yesterday”. Among his other accomplishments, Fr. Lemaître served as president of the Pontifical Academy of Sciences from 1960 until his death in 1966.
Click here for a preview from Google Books.
From the dust jacket of The Day Without Yesterday:
Sometimes our understanding of our universe is given a huge boost by one insightful thinker. Such a boost came in the first half of the twentieth century, when an obscure Belgian priest put his mind to deciphering the nature of the cosmos. Is the universe evolving to some unforeseen end, or is it static, as the Greeks believed? The debate has preoccupied thinkers from Heraclitus to the author of the Upanishads, from the Mayans to Einstein. The Day Without Yesterday covers the modern history of an evolving universe, and how Georges Lemaître convinced a generation of thinkers to embrace the notion of cosmic expansion and the theory that this expansion could be traced backward to the cosmic origins, a starting point for space and time that Lemaître called “the day without yesterday.” Lemaître’s skill with mathematics and the equations of relativity enabled him to think much more broadly about cosmology than anyone else at the time, including Einstein. Lemaître proposed the expanding model of the universe to Einstein, who rejected it. Had Einstein followed Lemaître’s thinking, he could have predicted the expansion of the universe more than a decade before it was actually discovered.
Also from The Day Without Yesterday:
[B]y the time Lemaitre had come to the fore with his expanding model of the universe, the opposition between science and religion had become fodder for journalists. And it’s interesting, for this reason, to go back to the early interviews with Lemaitre when he returned to California in 1933 and how he responded to the already typical question – just how did a priest-physicist reconcile his faith with his science?
The writers of the Bible were illuminated more or less – some more than others – on the question of salvation. On other questions they were as wise or as ignorant as their generation. Hence it is utterly unimportant that errors of historic or scientific fact should be found in the Bible, especially if errors relate to events that were not directly observed by those who wrote about them.
The idea that because they were right in their doctrine of immortality and salvation they must also be right on all other subjects is simply the fallacy of people who have an incomplete understanding of why the Bible was given to us at all.
You can already detect a note of impatience with Lemaitre’s answer, as in, Why should this be a question? But it was.
Mathematical Disquisitions – The Booklet of Theses Immortalized by Galileo
Book- 176 pages
- High school level and above
This 2017 book by Christopher M. Graney is the first complete English translation of an astronomical text written by scientists who stood opposite Galileo in the debate on the question of Earth’s motion. Galileo painted a very unfavorable portrait of Mathematical Disquisitions and its Jesuit authors, but the book itself turns out to be a competent scientific work and not much like Galileo’s portrayal of it.
From the publisher, the University of Notre Dame Press:
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.”
The treatise provides valuable insight into the astronomical debates of the seventeenth century, a time when the question of the Earth’s motion was still very much in flux. Whereas Galileo’s works are readily available, there are far fewer translations of works arguing the other side. Christopher Graney’s translation focuses on the mathematical and astronomical core of Locher’s work and is suitable for undergraduate students in courses on the history of science, philosophy of science, astronomy, and physics.
