Pope Leo XIV commemorated the 56th anniversary of the Apollo 11 moon landing on Sunday, July 20, 2025, by engaging with astronaut Buzz Aldrin and visiting the Vatican Astronomical Observatory at Castel Gandolfo 1 2 3. This significant day saw the Pontiff reflect on human ingenuity and the mystery of creation 1 2.
On the afternoon of July 20, Pope Leo XIV held a video call with 95-year-old Buzz Aldrin, the last surviving crew member of the Apollo 11 mission 5 8. During their conversation, the Pope and Aldrin reminisced about the historic 1969 moon landing, acknowledging it as an enduring testament to human ingenuity 1 2 3. They jointly reflected on the "mystery of Creation, its greatness and its fragility," drawing inspiration from the words of Psalm 8 1 2 3 8. Before concluding the call, Pope Leo XIV extended his blessing to Aldrin, his family, and his collaborators 1 2 3. Aldrin later expressed his gratitude on social media for receiving the "highest blessing," stating they prayed for "good health, long life, and prosperity for all humankind" 2 3.
Earlier on the same day, following the Angelus prayer, Pope Leo XIV visited the Vatican Astronomical Observatory, known as the Specola Vaticana, located at Castel Gandolfo 1 2 5. This marked his first visit to the observatory since becoming Pope 7 9. He explored the historic telescopes and instruments, accompanied by astronomers and students from the Vatican Observatory Summer School 7 9. The visit underscored the Church's long-standing commitment to scientific exploration, viewing it as a partner to faith 3.
The Vatican Observatory, founded in 1891 by Pope Leo XIII, has a history dating back to the 18th century and is staffed by Jesuit astronomers 3 5 7 8. It is renowned for its research and its impressive meteorite collection, which includes fragments from Mars 7 9. Pope Leo XIV himself holds a degree in mathematics and has previously expressed his appreciation for astronomy, urging young scientists to use their knowledge for the benefit of all and to share the "joy and wonder" of contemplating the universe 5 8.
This papal engagement continues a tradition of popes connecting with space exploration; previous popes, including Benedict XVI and Paul VI, have also communicated with astronauts 7 9.
Initially expected to return to the Vatican on Sunday, Pope Leo XIV extended his two-week summer stay at Castel Gandolfo until Tuesday, July 22, for further rest and study 2 3 5 8. The events of the day, particularly the conversation with Aldrin, were framed by the Holy See as a moment of prayer, emphasizing the sacredness of life and a broader call for peace in a world afflicted by conflict 10. Pope Leo XIV linked the wonder of creation to the urgent need to end the "barbarity of war," highlighting that violating human dignity offends God and destroys the "wonder of Creation" 3 10.
How does the Church view scientific discovery and creation?
The Catholic Church holds a high regard for scientific and technological research, viewing it as a significant expression of humanity's dominion over creation and a service to truth, goodness, and beauty . The Church believes that faith and reason are not in opposition but are like "two wings on which the human spirit rises to the contemplation of truth" .
The Church teaches that scientific inquiry, when rigorously focused on its specific field, does not contradict faith when it arrives at conclusions that reason cannot refute . Historically, figures from Copernicus to Mendel, and from Albert the Great to Pascal, demonstrate a scientific culture rooted in Christianity . Scientific research, by exploring the universe, contributes to the glory of God, which is reflected in every part of creation .
Pope John Paul II emphasized that if scientific research proceeds with rigorous methods and remains faithful to its object, and if Scripture is read according to the Church's directives, there can be no opposition between faith and science . Any historical conflicts have stemmed from erroneous positions or a shortsighted view of science's rightful autonomy .
Scientific endeavor is seen as a way for humanity to participate in the Creator's knowledge, serving as a "first degree of man's resemblance to God" . The discovery of the universe's laws and complexities through scientific observation can lead to wonder and draw individuals to the love of the Author of all things . As Romans 1:20 states, "Ever since the creation of the world his invisible nature, namely his eternal power and deity, has been clearly perceived in the things that have been made" . Through increased knowledge of the universe and humanity, one can perceive God's presence in the "silent manuscript" of creation .
Scientific and technological advancements are considered splendid testimonies to the human capacity for understanding and perseverance . The Church encourages scientific activity, recognizing its potential to benefit humanity by discovering unknown energies and putting them to man's service . This work should lead to the growth of both humanity and nature, humanizing man while respecting and perfecting nature .
However, the Church also stresses the importance of ethical principles in scientific research . Science cannot generate these principles on its own but must accept them to prevent potential pathologies . There is a concern that science might sometimes be driven by easy earnings or the "arrogance of replacing the Creator," which can be dangerous to humanity . Therefore, philosophy and theology are indispensable aids to ensure science remains on track in its service to human well-being and progress .
The Church advocates for dialogue between faith, reason, and science, especially in times marked by fragmented knowledge and a separation between truth and values . This dialogue, based on critical openness, aims to overcome unilateral or partial views of reality . Christians are encouraged to have an enlightened vision of the world, shaped by scientific findings, and to look at these findings critically and with depth . Conversely, scientists can benefit from the reflective depth of theological wisdom to find meaning and value in their lives and avoid absolutizing their results beyond reasonable limits .
