"Wonderful. Absolutely wonderful," Rev. Edward Kacerguis declared, taking in the crowd Feb. 28 at Christ Sun of Justice parish in Troy.

At the front of the room was a gigantic viewscreen. A cluster of people surrounded the reason for Father Kacerguis' enthusiasm: Jesuit Brother Guy Consolmagno, a planetary scientist who is director of the Vatican Observatory.

Brother Guy had just concluded a talk as part of the parish's annual, week-long Lenten speaker series.

Father Kacerguis told The Evangelist he'd been shocked when Brother Guy immediately accepted his invitation to participate in Christ Sun of Justice's Lenten program. The astronomer's presence was particularly apt because the parish is located on the campus of Rensselaer Polytechnic Institute (RPI), where students study ground-breaking science and technology.

Brother Guy had spent the day at RPI, meeting with graduate students, undergrads and members of the physics department and leading a colloquium in the afternoon before delivering his evening Lenten address.

All creation
Attendees at the talk were visibly moved by the photos he shared of planetary landscapes, moon craters, stars and galaxies. He was quick to note that none of the images were artist's renderings; close-up photos showed places "we have visited with our machinery and left our footprints."

The astronomer emphasized the need to see other heavenly bodies as specific places. He shared a clip from a panel discussion televised on C-SPAN after a Mars rover landing in which a rover team member described his awe at seeing photos of the red Martian landscape.

Brother Guy related all of this to faith.

"The study of the universe is an act of worship," he told the crowd, citing Psalm 139: "O Lord, you have searched me and you know me...."

"There are places in the universe we haven't set foot on yet, and maybe we won't," said Brother Guy, but they are "as much a part of God's creation" as the Earth.

"God is bigger than just what we see around here," he said.

Photos and faith
Throughout the talk, photos flashed by on the viewscreen:

•  the rocky surface of Venus, captured by a Russian lander that lasted only minutes in the 700-degree, high-pressure atmosphere where sulfuric acid fills the air;

•  Io, a moon of Jupiter with a yellow surface covered with erupting volcanoes;

•  "Earthrise," with the Earth seen from orbit, coming up from behind the moon.

Along with the pictures came quotes from St. Francis of Assisi's "Canticle of the Sun:" "Be praised, my Lord, through all your creatures, especially Sir Brother Sun...through Sister Moon and the stars...through Brothers Wind and Air...through Sister Water...through Brother Fire...through our Sister, Mother Earth...."

The canticle was composed in the year 1225, but Brother Guy said its spirit is just as applicable today. He pointed to "Laudato Si'," Pope Francis' encyclical on the environment, which expressed similar ideas about respect for creation. "We are made by God and we are siblings," the astronomer said. "To exploit nature is to exploit your little sister."

Brother's background
Brother Guy is a native of Detroit. He shared his own life story, from studying the moons of Jupiter to serving in the Peace Corps, teaching physics and, in 1993, coming to the Vatican Observatory, where he has studied meteorites and asteroids and now serves as director.

Though the observatory's headquarters are in the papal summer gardens at Castel Gandolfo, south of Rome, much of its work is done in Tucson, Ariz., where the Vatican Advanced Technology Telescope is located.

Brother Guy has also traveled to Antarctica to search for meteorites. He noted that the photos he took there resembled the surfaces of other planetary bodies: harsh, barren landscapes that, nevertheless, have much to reveal about creation.

Even the smallest cross-section of a meteorite -- smaller than a human hair -- shows incredible crystalline structures, he said, noting "that sense of discovery, that I've seen this little thing....It's like the voice of God behind me, saying, 'Isn't this cool?'

"This is what human beings do: You look at the sky and you say, 'Wow,'" he said. "That's why we do astronomy: because we are hungering for more than food, and we need to be fed."

After his talk, Brother Guy told The Evangelist that studying the stars makes the petty problems of life insignificant. "We get so provincial in thinking our problems are the world's problems. God who created the universe is perfectly capable of taking care of us," he said.

Recalling the way Americans had newfound appreciation for beauty in the wake of the 9/11 terrorist attacks, the astronomer said that, even in the worst of times, "you look at a sunset [and say], 'It's not all bad.' God is with us. Nature is fundamentally good. I've never seen an ugly astronomical image."
