Pope Leo XIV encouraged young astronomy students at the Vatican this week to “be generous in sharing what you learn and what you experience, as best you can and however you can.”
“Surely, this must be an exciting time to be an astronomer,” Pope Leo said to scholars at the Vatican on June 16. The students gathered as part of a monthlong astronomy and astrophysics summer school program hosted by the Vatican Observatory.
The biannual summer program is taking place at the observatory’s headquarters in Castel Gandolfo, Italy, where students come from across the globe to participate. The Vatican Observatory only accepts a small group of students in their final year of undergraduate studies or first year of graduate school.
Each summer the program has a different theme and area of study. The 2025 group is exploring the universe with data from the James Webb Space Telescope, which is currently the largest telescope in space. Pope Leo called it a “truly remarkable instrument,” according to the United States Conference of Catholic Bishops.
“Do not the James Webb images also fill us with wonder, and indeed a mysterious joy, as we contemplate their sublime beauty?” the pope asked.
Students will focus on the telescope’s contributions over the last three years to the evolution of galaxies, birth of stars, and planetary systems and the origin of life.
“For the first time, we are able to peer deeply into the atmosphere of exoplanets where life may be developing and study the nebulae where planetary systems themselves are forming,” Pope Leo said.
“The authors of sacred Scripture, writing so many centuries ago, did not have the benefit of this privilege, yet their poetic and religious imagination pondered what the moment of creation must have been like.”
Pope Leo discussed scientists’ ability to trace “the ancient light of distant galaxies,” which he said “speaks of the very beginning of our universe.”
Jesuit Brother Guy Consolmagno, president of the Vatican Observatory, told CNA that they “were thrilled that Pope Leo was able to meet with the students and faculty of our summer school.” He said “the students have told me how much they enjoyed, and felt honored by, the chance they each had to speak briefly with him.”
“From his remarks, it’s clear that he embraces our mission to find joy in the study of God’s creation,” Consolmagno said.
He also shared that he “was especially touched” by Pope Leo’s “reference to St. Augustine’s description of the ‘seeds’ God has sown in the harmony of the universe.”
“Each of you is part of a much greater community,” Leo told the young scientists.
“Along with the contribution of your fellow scientists, engineers, and mathematicians, it was also with the support of your families and so many of your friends that you have been able to appreciate and take part in this wonderful enterprise, which has enabled us to see the world around us in a new way.”
“Never forget, then, that what you are doing is meant to benefit all of us,” the pope added.
“The more joy you share, the more joy you create, and in this way, through your pursuit of knowledge, each of you can contribute to building a more peaceful and just world,” he said.
