The Vatican Observatory (VO) is a distinguished institution dedicated to astronomical research and public outreach, recognized as one of the oldest observatories in the world, with origins tracing back to 1582. Located at the papal summer residence in Castel Gandolfo near Rome, the Observatory operates under the auspices of the Vatican City State. It is staffed by a diverse team of priests, brothers, and adjunct scholars from around the globe, all committed to exploring the universe through modern scientific methods.

The Observatory is home to the Vatican Advanced Technology Telescope (VATT) situated in Arizona, which enables cutting-edge astronomical research. It plays a vital role in promoting education and facilitating a dialogue between science and faith, reaching over 5,000 individuals annually through presentations and outreach programs. The Vatican Observatory Foundation supports these initiatives, helping to foster a greater understanding of the cosmos while engaging the public with innovative educational resources. From studying interplanetary dust to exploring cosmic origins, the Vatican Observatory bridges faith and science in meaningful ways.
