Pope Leo XIV has encouraged young astronomers to share their knowledge and the joy of discovery with others, emphasizing its contribution to building a more peaceful and just world. The pope spoke during an audience at the Vatican Observatory in June, addressing dozens of university and graduate students from developing nations who were taking part in a monthlong summer school on astronomy and astrophysics.
The program, held every two years, focuses on exploring the universe with data from the James Webb Space Telescope, which has enabled scientists to study the birth of stars, galaxy formation, and the origin of life. The pope praised the telescope’s contributions to understanding the cosmos, saying it allows us to “peer deeply into the atmosphere of exoplanets” and “trace the ancient light of distant galaxies.”
Pope Leo XIV reminded the students that scientific discovery should benefit all humanity, not just a select few. He urged them to share their knowledge, experiences, and the joy of discovery with others, highlighting its potential to create more joy and contribute to building a more peaceful world.
The pope also emphasized the importance of community and collaboration in scientific pursuits. He acknowledged the contributions of families, friends, and fellow scientists who have supported students in this endeavor, encouraging them to remember that their work benefits everyone. By sharing their knowledge and passion for astronomy, young astronomers can make a positive impact on society and create a more just and peaceful world.
