This entry is part 40 of 190 in the series Across the Universe

My columns for The Tablet often act as a diary of sorts, recording important events in science or in my own life. Such is this column, which first ran in September, 2006. We first ran it here in 2015. Ten years ago last month [as of 2006 – now 23 years ago!], Dave McKay and his colleagues at NASA’s Johnson Space Center in Houston announced that a meteorite, believed to have come from Mars, showed evidence of microbial life. Their interpretations are still widely disputed by the meteoritics community. But, oddly, their announcement resulted in one major change of attitudes. Before, there were still skeptics who were not sure that those rocks came from Mars; now, as the skeptics argue about the putative biogenic grains found in it, no one doubts the Martian origin anymore! Some of us can only be skeptical of one thing at a time, I guess. Still, what you call the meteorite doesn’t really change its … Continue reading →

Light Thinking

Sacred Space Astronomy avatarPosted on by

It’s raining as I write, water pours down the window like syrup in a jar. Montbretia in the garden seem to generate self-made light. Each flower punctuates the greyness with orange flames on stems within the hedgerow. It is often grey days that send me light thinking and remind me of how frequently I dwell on it. Recently I met Br Guy Colsolmagno for breakfast in Dublin. A sunny morning with the promise of more light to fill the day. We had a fun catch up chat within which were several moments of encouragement  sprinkled  towards my work. We then headed to the National Gallery of Ireland to see an impressionist exhibition. Sorolla Exhibition Sorolla was a Spanish master of light, the exhibition held fifty works spread over four large rooms in the gallery. All of Sorolla’s work in which the subjects were sails, sailing or water  mesmerised  me. I enjoyed his brush strokes, bold one stroke renderings of shirt … Continue reading →

Across the Universe: Friends in high places

This entry is part 76 of 190 in the series Across the Universe

This column first appeared in The Tablet in June, 2008; we first ran it here in 2016 The Mars Phoenix mission landed successfully near the north pole of Mars [in 2008]. Even though I don’t study Mars myself, I feel a special connection because the mission is being run out of my old department at the University of Arizona. I know those guys on the TV, explaining how they’ll be digging for ice in the Martian soil. Mars wasn’t the only tourist attraction that summer. The scientists of the Cassini/Huygens Saturn probes held a team meeting in Rome in June, 2008, and two dozen of them came out to visit me at Castel Gandolfo. I showed them our telescopes and libraries and meteorite collection. Friends of mine on the team arranged the visit. Why do I have so many friends in high places? It’s just the nature of my field. There are only a few thousand professional planetary astronomers in the world. We … Continue reading →

Across the Universe: Truth, Beauty, and a Good Lawyer

This entry is part 27 of 190 in the series Across the Universe

This column first appeared in The Tablet in May, 2007; we republished it here in May, 2015 In 2006-2007, I took a year-long chair at Fordham University, where I was required to present a public lecture each semester. In the fall term, I simply gave a reading from my latest book-in-progress. But the spring was trickier. Mostly I wanted an excuse to show pretty pictures; why else did they hire an astronomer to speak? Looking for an academic hook to hang my talk on, I decided to use these images to explore the nature of beauty. What makes pictures of stars and planets beautiful? Is a human connection – the astronaut in the frame, the dot in the background that’s actually planet Earth – necessary for us to awed by nature? Does knowing the science behind the image add to its beauty? These questions had been inspired by my ongoing conversations with a Fordham philosophy professor, Sister Joan Roccasalvo CSJ. Her take centers on … Continue reading →

Across the Universe: Seeing the Light

This entry is part 26 of 190 in the series Across the Universe

This column first appeared in The Tablet in April, 2007; we ran it here again in May, 2015 The e-mail came from the Fordham student who’s been working in the lab with me this term. “Some of the physics students have asked me to pass this on to you: they don’t want to admit it, but they’re totally lost.” There’s only a couple of weeks left of my sabbatical year at Fordham. I had asked the physics department if I could teach the class on electricity and magnetism; when I learned this material myself as an undergraduate, it had changed my life. I wanted the opportunity to pass the joy on to some of the brightest kids I’ve ever taught. They are totally lost? That’s no surprise; when I was a student, at this point I was lost too. The mathematics of electromagnetic fields has mystified science undergraduates even before Maxwell first summarized them with his famous equations. And the … Continue reading →

Across the Universe: The Exploding Centaur

This entry is part 25 of 190 in the series Across the Universe

This column first appeared in The Tablet in April, 2006, and first published here in 2015. It was April Fool’s Day at the Vatican’s telescope in southeastern Arizona, and we’d had three nights of cloudy weather. This night looked promising, however. Bill Romanishin, our colleague at the University of Oklahoma, had given us a list of Kuiper Belt Objects to observe, orbiting out beyond Neptune. Included were some Centaurs, objects that some day might become comets plunging close to the Sun. At the telescope, I was with Steve Tegler from Northern Arizona University. Along with each object, we also observed bits of blank sky, so we could find and remove all the dust spots on the images; and fields of stars whose colours and brightnesses were already well known, so that we could calibrate our objects against these known standards. Around midnight, about halfway into a field of standard stars, Steve looked over his list again and remembered, “Oh, Bill wanted us … Continue reading →

Across the Universe: Orbiting a New Sun

Fourteen years ago this month, Pope John Paul II died and Pope Benedict XVI was elected. I wrote this column in reaction to those events; it appeared in the Tablet in April, 2005. We republished here in 2015, the tenth anniversary of the event. For twelve years [as of 2005] I have been an astronomer at the Vatican Observatory, one of a dozen Jesuits who are guests of the Pope at his summer home in Castel Gandolfo. And as an astronomer I observed John Paul II: occasionally in close encounters, more commonly from a distance… brief glances, an amplified voice resonating through the window of my room overlooking Wednesday audiences, Sunday Angelus prayers, and Mass for a thousand different groups of visitors. Our orbits rarely intersected. At Castel Gandolfo, our living quarters and offices are under the same roof as the Pope’s, but in fact our paths (like our hallways) rarely intersect. He’d have the Jesuits over for Mass on … Continue reading →

Across the Universe: Limits to Understanding

This entry is part 23 of 190 in the series Across the Universe

First published in The Tablet in February, 2008; we ran it here in 2015. I’ve moved it to March this time around, to fit the Lenten theme at the end. The American Association for the Advancement of Science (AAAS), a prestigious umbrella group of American scientists, convened this past weekend [2008] in Boston. At the same time, in a hotel on the other side of town, a few hundred science fiction fans were gathered to meet their friends and talk about their favorite writers. I sat on science-and-religion panels at both conventions. The AAAS panel was concerned about “Communicating Science in a Religious America.” In spite of several legal victories by the scientific community defending the teaching of evolution in public schools, the “Intelligent Design” movement in America is still winning the public relations wars. Barely half of polled adults there say they believe in evolution, the lowest numbers of any industrialized nation. Though no one on the panel put … Continue reading →

Across the Universe: One Fix Leads to Another

First published in The Tablet in February, 2007; we first ran it here in 2016. I’ve moved it to March, this year, to fit the Lenten season. With my colleague Dan Britt from the University of Central Florida, for several years I’ve been measuring the densities and porosities of meteorites. The densities of different meteorite classes can be compared with their parent asteroids, to see how loosely packed they are; and the porosity of these rocks is an indication of how thoroughly their fabric has been cracked by the shock of the impacts that shattered those parent bodies. We started with the collection I curate at the Vatican; but there are many meteorite types that are underrepresented there. When I came to New York [in 2007] for a year’s sabbatical at Fordham University, I had hoped to extend our data by looking at the nearby American Museum of Natural History’s extensive collection. But things got off to a slow start. … Continue reading →

Across the Universe: The best way to travel

This entry is part 20 of 190 in the series Across the Universe

First published in The Tablet in January, 2007; we first ran it here in 2015.  Dark and dreary, January is a time to take off to new and exotic climes; or at least, to daydream about such trips. My own January voyage was a visit to my old hometown, snow-dusted Detroit, to attend a science fiction convention. But a panel discussion at that meeting, “Travel Destinations of the Solar System,” challenged us to imagine really exotic localities. Where among the planets would we love to go? And what it would be like to be standing there, in person? Panelist Bill Higgins, a radiation physicist at Fermi Lab in Chicago [and occasional blogger here at The Catholic Astronomer!], regularly presents spaceflight results as a NASA “Solar System Ambassador” at events like this. He described how Pluto and its moon Charon orbit each other while locked in a spin state that keeps each body always facing the other. “What if we could … Continue reading →

Across the Universe: Stardust messages

This entry is part 19 of 190 in the series Across the Universe

First published in The Tablet in January, 2006; we ran it here in 2015. Thirty [now more than 40!] years ago, when I was a doctoral student at the University of Arizona, our campus in Tucson lay beneath the landing path of the Davis-Monthan Air Force Base and every few minutes our planetary science classes would be interrupted by the roar of a jet fighter. But an occasional plane would cross overhead with a different sound… an odd, almost quiet whine. Looking up you’d see the large black cruciform, long straight wings and a thin fuselage, of a U-2 spy plane. For twenty years they’d flown photography missions over Soviet Russia and other cold war hotspots. But one U-2 was different. Rather than spooky black, it was painted pure white. And instead of air force emblems, it flew NASA insignia. A visitor to our Lunar and Planetary Laboratory, Don Brownlee from the University of Washington, explained those flights to us. … Continue reading →

Across the Universe: Desert or a dessert?

This entry is part 18 of 190 in the series Across the Universe

First published in The Tablet in January, 2005, just after the Huygens probe landed on Saturn’s moon Titan. We ran it again here on January, 2015. This text is based on what I submitted, which was edited for length when it was printed.   The most remarkable thing about the images from Saturn’s moon, Titan, which ESA’s Huygens probe has just sent us, is how “familiar” they look. They remind me of Nadar’s 19th century Collodion “wet plate” photographs taken from a balloon above Paris. Black and white, a bit fuzzy, these patterns of light and darkness can be grasped and processed by imagination and memory until we impose meaning on them. I picture myself floating through the clouds, gazing across at an intricate pattern of riverbeds cutting through rough light-colored mountains, flowing down to a flat, wine-dark sea. If these are riverbeds – and they certainly look like textbook examples of the many-branched “dendritic channels” made by rainfall flowing down hills … Continue reading →
