The Vatican Observatory
The Vatican Observatory is an institution established by the Holy See for astronomical research and public outreach to advance the scientific understanding of our universe.
The Vatican Observatory is one of the oldest active astronomical observatories in the world, with its roots going back to 1582 and the Gregorian reform of the calendar.
The Vatican Observatory stands at the forefront of scientific research covering a broad range of topics, from an examination of the tiniest specks of interplanetary dust to the origin and structure of the universe.
Headquartered at the papal summer residence in Castel Gandolfo, outside Rome, this official work of the Vatican City State supports a dozen priests and brothers (Jesuits and diocesan) from four continents who study the universe utilizing modern scientific methods.
The Vatican Observatory works with the Vatican Observatory Foundation to promote education and public engagement in astronomy, and constructive dialogue in the area of faith and science.
