About Br. Guy Consolmagno

Brother Guy Consolmagno SJ is Director of the the Vatican Observatory and President of the Vatican Observatory Foundation. A native of Detroit, Michigan, he earned undergraduate and masters' degrees from MIT, and a Ph. D. in Planetary Science from the University of Arizona; he was a postdoctoral research fellow at Harvard and MIT, served in the US Peace Corps (Kenya), and taught university physics at Lafayette College before entering the Jesuits in 1989.

At the Vatican Observatory since 1993, his research explores connections between meteorites, asteroids, and the evolution of small solar system bodies, observing Kuiper Belt comets with the Vatican's 1.8 meter telescope in Arizona, and applying his measure of meteorite physical properties to understanding asteroid origins and structure. Along with more than 200 scientific publications, he is the author of a number of popular books including Turn Left at Orion (with Dan Davis), and most recently Would You Baptize an Extraterrestial? (with Father Paul Mueller, SJ). He also has hosted science programs for BBC Radio 4, been interviewed in numerous documentary films, appeared on The Colbert Report, and for more than ten years he has written a monthly science column for the British Catholic magazine, The Tablet.

Dr. Consolmagno's work has taken him to every continent on Earth; for example, in 1996 he spent six weeks collecting meteorites with a NASA team on the blue ice regions of East Antarctica. He has served on the governing boards of the Meteoritical Society; the American Astronomical Society Division for Planetary Sciences (of which he was chair in 2006-2007); and IAU Commission 16 (Planets and Satellites). In 2000, the small bodies nomenclature committee of the IAU named an asteroid, 4597 Consolmagno, in recognition of his work. In 2014 he received the Carl Sagan Medal from the American Astronomical Society Division for Planetary Sciences for excellence in public communication in planetary sciences.

Across the Universe: Fast changes

This column first ran in The Tablet in June 2013 Summer began [in 2013] on Friday morning, 21 June, at 5:14 am GMT…in the northern hemisphere, of course; south of the equator, it’s winter. [The summer solstice 2017 in Northern Hemisphere occurred at 4:24 am GMT on Wednesday, June 21.] This definition is based on the precise orientation of the Earth in its orbit. The Earth is tilted relative to its orbit, and like a gyroscope its spin axis stays pointed in the same direction, year round. In a convenient coincidence for navigators, our north pole is pointed near the star Polaris. Polaris is not directly above the Sun; it’s directly above Earth’s tilted spin axis. In June, the Earth is in the part of its orbit where it’s on one side of the Sun, and Polaris is on the other side. The northern half of the Earth, tilted towards Polaris, is also tilted towards the Sun; that’s why it gets warmer. The … Continue reading

An interfaith fellowship on religion and science

It comes in the mail… This might be very interesting to the readers of our blog… with Rabbi Geoff Mitelman’s permission, I am posting here his email to me: I’m writing to you because my organization, Sinai and Synapses, bridges the worlds of religion and science, and aims to elevate the public discourse in general. We have just opened applications for an interfaith Fellowship on religion and science, where we will bring together a select group of academics, clergy and writers for learning, networking and content creation in New York six times over two years. Through a generous grant, we will also be able to cover travel for all the meetings, (within North America). We want to make sure we have a diverse collection of Fellows, so I wondered if you might know people who would be good candidates to apply, or even if you could share it in your networks. Obviously, we can’t promise anything, since we don’t know how many … Continue reading

Across the Universe: Ephemeral science

  This column first ran in The Tablet in June 2016 Over the past thirty years the Vatican Observatory in Castel Gandolfo has been hosting a biennial summer school, where we invite young scholars from around the world to spend four weeks with us, exploring in depth some topic in astrophysics. [The 2016] school was centered on water in the solar system and beyond. It’s an area that I’ve worked in since I was a young scholar myself; my master’s thesis, now more than 40 years old, was all about Jupiter and Saturn’s icy moons. All of my work on the topic, of course, is long obsolete. Just four years after I had made my computer models to predict what we’d see at those moons, the Voyager spacecraft actually visited Jupiter and revealed its moons to be worlds far more elaborate than anything I could have proposed. Still, the basic science hasn’t changed; at our school we taught how to use properties like … Continue reading

Across the Universe: Of stars and sheep

This column first ran in The Tablet in June 2015 ‘Today we can illuminate our cities so brightly that the stars of the sky are no longer visible. Is this not an image of the problems caused by our version of enlightenment? With regard to material things, our knowledge and our technical accomplishments are legion, but what reaches beyond, the things of God and the question of good, we can no longer identify.’ — Pope Benedict XVI At Notre Dame University [in June 2015], Katharine Mahon, a doctoral student in theology, reminded me of this passage from Pope Benedict’s Easter 2012 homily. One of the striking hallmarks of Pope Francis’ encyclical on the environment, Laudato Si’, was how it was rooted in the theology and writings of his predecessors, like the passage above. Just as our badly-overlit cities blind us to the stars, our desire to wrap ourselves in the soft wool of technology insulates us from the reality of … Continue reading

Across the Universe: Jesuit Science

This column first ran in The Tablet in June 2014 [In 2014] Heythrop College celebrated its 400th anniversary. Originally founded in Belgium to educate British Jesuits, it moved back to England during the French Reign of Terror. Located since then at various locations, it finally moved to London in 1970, becoming a part of the University of London in 1971. An anniversary like this calls for a party, of course. On June 19-20, hundreds of scholars gathered at Senate House to reflect on Jesuit scholarship. Among the celebrants were Lord Williams and Jesuit Father General Adolfo Nicholas. I was invited to talk on Jesuit science. [The link above is the recording of my talk, and runs about 55 minutes; in my opinion, it’s more entertaining than this column was!] What has been the particular Jesuit mark on science? One thing that struck me was how entering the Jesuits order gave young men the chance to be a scientist regardless of family … Continue reading

Faith and Science: One Stop Shopping!

We’re pleased to announce the latest outreach project of the Vatican Observatory Foundation: A Faith and Science resource site (click here!) The idea is to have a place where Catholic educators – and educated Catholics – can go to find links to materials all over the web dealing with a variety of topics on the broad issue of Faith and Science. This web site is not complete, of course, and probably never will be… new material is being posted (and being brought to our attention) all the time. In fact, when you go to the site you’ll notice a certain bias towards material that our own members of the Vatican Observatory, past and present, have prepared and posted on-line. Rather than describing it further, I encourage you to go explore the site itself. And if you have comments or suggestions, please let us know. However, there’s one point I do want to make here. Sites like these don’t happen for … Continue reading

Hymns of Faith and Science

A few years ago, I gave an astronomy-themed retreat in the UK and among those attending was Trevor Thorn, who among other things writes hymns. He shared a few of his astronomy-themed hymns with me. Now, I’ll be honest, I find most such mash-ups tend to be pretty cringe-worthy. So I was all the more surprised to read his; they were very good… as you can see, on his blog site, The Cross and the Cosmos. (Which also includes a lot of other faith/astronomy themed art.) One particular bunch were written with kids in mind, and they’re quite fun. He’s “test-run” some of his songs with local church schools in Cambridge. Here’s a short video about that effort: … Continue reading

Across the Universe: Song of Praise

This column first ran in The Tablet in May 2016 When Pope Francis issued his groundbreaking encyclical, Laudato Sì, the Italian publishing house Elledici took the moment to reissue a book written in the 1960s by the Italian scientist Enrico Medi: Canitco di Frate Sole, a meditation on the Franciscan poem that gave Pope Francis his title. At that time, they asked me as the “Pope’s astronomer” to write an introduction for the book. On first anniversary of the Pope’s encyclical, in 2016, I was invited to Medi’s home town of Senigalia, on the Adriatic coast, to celebrate the publication of this book. I’d never heard of Medi; but I discovered that he was the spokesperson of his generation in Italy on faith and science. Reading his words, even with my poor Italian, I can see why. For example, in one chapter Medi begins with our scientific understanding of water as a marvelous molecule, but he arrives at finding in … Continue reading

Across the Universe: Shapes of Things

This column first ran in The Tablet in May 2015 In May of 2015, the Lunar and Planetary Laboratory of the University of Arizona honored the retirement of Dr. Randy Jokipii, Regent’s Professor of Planetary Sciences… and the man who directed my doctoral dissertation. It’s customary at such events to downplay the scientific work of the honoree, and praise instead the “life lessons” taught. But Randy was not my father, my pastor, or my guru; he taught me physics. I chose to work for him for the simple reason that I thought he was the smartest guy in the department. (I still think so.) His field, cosmic ray physics, was far from what I had done before… or since. That was another attraction: I wanted to be challenged to learn new stuff. I got what I wanted. Under his direction I spent two years applying techniques that he’d invented for tracing cosmic rays in solar system magnetic fields, to the … Continue reading

Across the Universe: Expect Surprises

This column first ran in The Tablet in May 2014 In a recent [2014!] homily, Pope Francis used a colorful image to describe how the early Church reacted when gentiles approached the apostles and asked to be baptized. Imagine, he suggested, if “a Martian with a big nose and big ears came up and asked for baptism. What would you do?” Naturally, the press decided that the Pope had just endorsed extraterrestrial baptisms. Journalists with access to the internet added a few choice links to similar quotes of mine from years ago. I can’t complain, really. “Would you baptize an extraterrestrial?” is a wonderful starting place to explore the meaning of baptism and redemption. I used the analogy myself in May of 2014, addressing the graduating class of Georgetown University, where my final exhortation was to “be prepared to be surprised.” (Not surprisingly, we have a book with that question as its title, which came out in fall 2014.) But a … Continue reading

Across the Universe: A Thousand Stars are Born

This column first ran in The Tablet in May 2013 Cygnus OB2 is an association of perhaps a thousand young, massive stars, some of them a hundred times more massive than the Sun and a million times brighter, immersed in a much larger molecular cloud known as Cygnus X. Because it is so close to us (“only” 4700 light years away) we can study Cygnus OB2 in detail, comparing model predictions about the formation of such massive stars with actual observations. These studies might help us understand how such stars are born not only in our galaxy but also in more distant galaxies. But that mass of data can overwhelm our understanding. It’s impossible for any one astronomer to keep track of all the latest developments. And so in May, 2013, we held a workshop at the Vatican Observatory in Castel Gandolfo where two dozen scientists could compare notes about this star formation region. “This is a meeting of the blind … Continue reading

Across the Universe: Edge of the World

  This column first ran in The Tablet in April 2015 At the edge of the world, the top of the world, is a window of our world into the rest of the universe: the telescopes of the European Southern Observatory (ESO) in Chile. Nearby are other large observatories at Cerro Tololo, Las Campanas, and the Alma radio array at Chajnantor. These telescopes have shown how the expansion of our universe is accelerating; they’ve explored hundreds of planets around other stars; they’ve traced the motions of stars orbiting a super-massive black hole at the center of our Milky Way galaxy. I am visiting [in 2015] here with a half-dozen patrons who support such telescopes (including the Vatican’s own telescope in Arizona). Along with our host, Dr. Fernando Cameron, our small group includes a businessman who sits on the boards of universities; a retired schoolteacher; a NASA engineer… eclectic in background, but joined by a fascination of the bigger universe, and the … Continue reading
