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: Happy Birthday to Us

This column first ran in The Tablet in March 2016 It has been a month of anniversaries. Exactly four hundred years ago (2016) Galileo first got into hot water with the Church over the Copernican system. Starting with a hearing of the Holy Office on 23 February, the affair stretched across all of spring 1616 including Galileo’s meeting with Cardinal Bellarmine on 26 February, and the formal censure of Copernicus’ work issued on 5 March. Curiously, Galileo’s works were not mentioned at that time. (It wasn’t Galileo’s first run-in with the Church. In 1604 he had been turned in to the Inquisition by his mother, who didn’t like the bad names he’d called her or the fact that he’d skip Mass to spend time with his courtesan girlfriend, later mother to his three children.) By the end of the 19th century, of course, the Church view on astronomy had changed. Pope Leo XIII in his encyclical Aeterni Patris (1879) essentially … Continue reading

Across the Universe: Spotting Ceres
avatar

This column first ran in The Tablet in March 2015 Ceres was the first body found in the region between Mars and Jupiter now called the Asteroid Belt. In the late 1700s Titius and Bode had noted a pattern in planet positions that suggested there should be a planet in the gap between Mars and Jupiter; on New Year’s Day of 1801, Father Giuseppi Piazzi found Ceres from his observatory in Sicily. They expected a planet, so that’s what they called Ceres – though William Herschel, who had just discovered the gas giant Uranus, sniffed that such a tiny dot of light was neither planet nor star (Latin, “aster”) but a mere “asteroid.” Only fifty years later, when a number of other such small bodies had been found, did Ceres and the other asteroids get “demoted” to the status of “minor planet.” (And later work showed that the Titius-Bode pattern which predicted a planet at Ceres’ position was actually just … Continue reading

Should you (or someone you love) go to MIT?

Today is “PI” day (written in American style, 3/14…) and MIT is holding a one day fundraiser… In honor of this day, this provides me with an excuse to post something I wrote for my Live Journal account a few years ago and which I get asked about from parents (and grandparents) of prospective students all the time. Of course the MIT I attended was nearly half a century back, but things haven’t changed all that much… Do I recommend MIT? Only if you are a very particular type of student. There is a reason why schools like MIT are so rare: because for most people, it is the wrong school to go to. MIT is not a place to find yourself. Because it is such an intense environment, it can be devastating to anyone who doesn’t already have a strong sense of who they are, and where they want to go. (Mind you, after MIT is finished with you, the person … Continue reading

Across the Universe: The Boundaries of the Unknown
avatar

This column first ran in The Tablet in March 2014 Isaac Newton thought that planetary orbits in our solar system were kept stable by God’s direct intervention; they were proof to him that God existed. A hundred years later, the great French mathematician and skeptic Pierre-Simon Laplace described his new orbital theory to Napoleon and supposedly quipped of God’s role, “I have no need for that hypothesis.” In fact, it is bad theology to reduce God to merely a gap-filling hypothesis. Only recently, however, have we learned that, actually, planetary motions may sometimes not be so stable after all. One of the pioneers of studying chaos theory in celestial dynamics is Jack Wisdom, an MIT professor (and MacArthur “genius”) who is visiting the Vatican Observatory this month. He’s working now on modeling the complex interaction between the Moon’s orbit and spin with the spin and orbit of the Earth. It’s all tied to the larger issue of the origin of … Continue reading

On Operas and Stars, Aliens and Refugees

I was recently in correspondence with Carl Pennypacker at Berkeley. To quote Wikipedia: “Dr. Pennypacker has spent much of his career as a research astrophysicist, receiving his Ph.D. from Harvard in 1978. His principal research was the studying of supernovae and the building of techniques for their automated discovery. With Rich Muller, he co-founded the Berkeley Supernova Search, which later became the Supernova Cosmology Project. He shared the 2007 Gruber Prize in Cosmology and the 2015 Breakthrough Prize in Fundamental Physics for the Supernova Cosmology Project’s discovery that the expansion of the universe is accelerating.” All true. But in addition to that, he has a deep interest in science outreach… and music. When he shared with me a video he’d been involved with (see below) I asked if I could post it here, and if he would give me a few words of introduction. He graciously agreed to both. He writes (edited from a couple of emails): I was part of “The Global Skylight” opera, as part of the IAU’s … Continue reading

Across the Universe: Faith and Expectations
avatar

This column first ran in The Tablet in March 2013, soon after the election of Pope Francis How do I feel about a Pope who is not only a fellow Jesuit, but one who’s studied science (in his case, chemistry) as well? To be honest, I am terrified. For the past twenty years I have lived off the expectations that others have of Jesuits and scientists; now I am going to have to deal with someone who can see past the mystique. Familiarity breeds a certain discomfort. I can only imagine what it’s like for our Observatory’s director, Fr. Funes, who is himself not only a Jesuit and scientist but also from Argentina. [In fact, as it later came out, when José first began the process of entering the Jesuits as a young man, one of the Argentinian Jesuits who interviewed him was a certain Father Bergoglio…] Pope Francis’ chemistry background has not gone unnoticed in the scientific world. A … Continue reading

The Beer and the Telescope

During a bout of insomnia Thursday morning, around 2 am, my phone buzzed with an incoming email from the editor of L’Osservatore Romano asking if I could get them an article about the TRAPPIST-1 planets. By noon. Italian time. So I stayed up another hour — I wasn’t getting any sleep anyway — and shipped one off to them by 3 am Tucson time. It ran in the Feb 23 edition… click here for a link. Of course, they translated it into Italian. Here is the original English text that I sent them… they edited it slightly. Last year, a team of astronomers led by Michaël Gillon of the STAR Institute at the University of Liège in Belgium announced the discovery of three planets around a star observed by one of their telescopes, TRAPPIST South. This week they have published new results in the scientific journal Nature that expands the number of planets in this system to seven. Brother Guy Consolmagno SJ, director … Continue reading

From The Tablet: Precisely Strange
avatar

This article first ran in The Tablet in February, 2016 At the museum of the history of science in Florence, honoring its famous local son Galileo, one can find a marvelous display of a 17th century high technology peculiar to Italy: fine glasswork. Consider the bubble-free glass that Galileo needed for his telescope lenses, the “Florentine flasks” beloved of chemists, the elaborate thermometers of the “Accademia del Cimento.” Italian glass technology made Italy the birthplace of the scientific revolution.  But a century later, as displayed in another room in this museum, mechanical devices produced in Britain and Germany allowed measurements of our universe to a much higher precision. With such instruments, those nations overtook Italy in the world of modern science. The February 2016 announcement of the observation of gravitational waves demonstrates again how our knowledge of ourselves and our place in the universe is advanced by our ability to measure nature ever more precisely. To detect the tiniest ripple in the space-time continuum, … Continue reading

Another blog about the blog

I just finished up giving a three-day astronomy-themed retreat (well, Friday night to Sunday noon) at the Jesuit Retreat Center in Los Altos, California. We had about 70 people show up, all of them impressive and enthusiastic and fascinating to meet. I wish I could have spent five hours with each of them. And someone in the group was kind enough to advertise The Catholic Astronomer, so I hope some of you from that retreat have found yourself here. But that also reminded me that I do need to do some occasional advertising. At the moment, the number of people who are signed up to get free emails when a new article is posted is just under 500; it should be at 5000, I would think. Tell your friends and neighbors about this site! (And your classes.) And don’t forget to sign up yourself. And if you have the wherewithal, joining Sacred Space would let us keep funding this site … Continue reading

Across the Universe: Global warning
avatar

  This column first ran in The Tablet in February 2015 My travels started in Boston, hit by a record number of massive snowstorms this winter; yet another blizzard trapped me inside the convention hotel all weekend. During a lull between storms, I was able to catch a flight to California… where the occasional flooding downpour failed to put an end to a five year drought. Climate is not the same as weather, but weather certainly reflects climate. And our climate is in serious trouble. It’s not just the anecdotal bad storm; it’s the sustained change in weather patterns – five years of drought, for example – that is finally getting our attention. One of the most common questions I get asked (just behind baptizing extraterrestrials!) deals with climate change. I give the same answer everywhere; the reaction I get varies wildly with the venue, however. Most of my questioners have already made up their mind that global climate change … Continue reading

Across the Universe: What good is God?
avatar

  This column first ran in The Tablet in February 2014 “What Good is God?” was the title of the 2014 Bannan Institute Program at Santa Clara University, the Jesuit school in California’s Silicon Valley. This month they invited me ask: why does science need God? I proposed that the answer is found in a different question. Why do we do science?   What do we hope to achieve when we decide to be a scientist? What counts as success? Tenure, prizes, citations in the literature… are those the ultimate goal of science? And what motivates us personally to choose to do science, instead of going into banking or selling neckties? Maybe it’s the pleasure in finding patterns and solving problems; doing science is like being paid to solve jigsaw puzzles. But is that our ultimate goal? Would we give up tenure for the chance to work on a really fun puzzle? Certainly science is a search for truth. In real life, … Continue reading

Across the Universe: View from afar
avatar

  This column first ran in The Tablet in February 2013 I traveled to Tucson to measure the fluctuating brightness of some small bodies in the outer solar system using the Vatican’s Advanced Technology Telescope. 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. (We got three clear nights out of five.) Data in hand, our work is still … Continue reading
