Newsroom, June 16, 2025, Gaudium Press – On June 16, 2025, Pope Leo XIV addressed astronomer students and scholars at the Vatican Observatory’s Summer School of Astrophysics, held in the Consistory Hall. Welcoming participants from around the world, the pontiff praised their commitment to exploring the universe through the James Webb Space Telescope (JWST), the focus of this year’s program. His remarks highlighted the harmony of science, faith, and human connection, urging young astronomers to share their discoveries for the benefit of humanity.
The Vatican Observatory, a historic center for astronomical research, has hosted its Summer School biennially since 1986, fostering collaboration among emerging scientists. This year’s theme, “Exploring the Universe with the James Webb Space Telescope,” celebrates the JWST’s transformative impact on astronomy since its 2021 launch. The telescope’s ability to probe exoplanet atmospheres, examine star-forming nebulae, and capture light from the universe’s earliest galaxies has redefined cosmic exploration.
In his address, Pope Leo XIV marveled at the JWST’s revelations, noting its capacity to reveal “the ancient light of distant galaxies, which speaks of the very beginning of our universe.” He referenced the Book of Baruch, where stars “shone in their watches and rejoiced” at their creation, suggesting that the telescope’s images inspire similar awe today. “Surely, this must be an exciting time to be an astronomer!” he declared.
The pope emphasized the collaborative nature of scientific achievement, acknowledging the decades of work by scientists, engineers, and mathematicians behind the JWST. He also recognized the support of the participants’ families and friends, reminding them that their work is part of a broader human endeavor. “Never forget, then, that what you are doing is meant to benefit all of us,” he urged, encouraging them to share their findings and the “mysterious joy” of cosmic discovery.
Quoting Saint Augustine, Pope Leo XIV spoke of the “seeds” of harmony sown by God in the universe, urging students to spread the wonder inspired by their research. He framed their pursuit of knowledge as a means to foster a “more peaceful and just world,” aligning scientific inquiry with the Vatican’s mission of global unity.
The address concluded with a blessing in English, invoking “wisdom and understanding, joy and peace” upon the participants and their families. The event, attended by dozens of students and faculty, underscored the Vatican’s enduring commitment to bridging faith and science, a tradition upheld by the observatory since 1891.
