All About Vatican City Telescope & Castel Gandolfo Observatory


Castel Gandolfo is a town located to the southeast of Rome, and has been the place where the Pope traditionally spends summer. The 135 acre Papal Summer Palace estate – known in Italian as the Palazzo Apostolico di Castel Gandolfo – is found here.

But the 8000 person town is also home to the Vatican Observatory. But what’s it all about? Let’s find out together.

The History of Vatican Telescope & the Vatican Observatory Foundation

The Observatory is an educational research agency funded by the Vatican State. It is really no surprise that the Vatican Church holds an avid interest in the planets and the stars. Typically, holy days and even Easter are calculated based on astronomical data, as was the Gregorian calendar.

The Observatory of the Roman College and other similar institutions operated in the 18th and 19th centuries in Rome in the name of the Vatican, but by the end of the 19th century these had come under the control of the Italian state.

In 1891 Pope Leo XIII established another Vatican Observatory within the walls of the Vatican city. This institution became a leading establishment within the study of astronomy, however as Rome modernised the smog and light pollution generated from the growing city made it difficult. Eventually it was moved to Castel Gandolfo, but by 1960 the same problems were beginning to happen there too!

That is why the Vatican Observatory Research Group (VORG) is now located in Arizona at the University of Tucson. The centre of the Observatory administration however remains at Castel Gandolfo

Staffed by Jesuit Priest astronomers, one of the main tasks of the telescope is to look for evidence that shows that Catholicism and Science are not necessarily in conflict with each other. Tasked with observing galaxies far away, those working in the institute use computers to help them track the night sky.

There is a group dedicated to planetary science, focussing on small objects. There is a meteoritics section, looking at how dense meteors are, as well as a Near Earth Observation Section, which identifies potentially dangerous objects.

Thoughts on Conspiracy Theories, Aliens & More

Not unsurprisingly – as is common with the Vatican City – there are a number of conspiracy theories that bounce around regarding the VAAT.

One of the most popular is that the Vatican owns a telescope called Lucifer. Espoused by fringe group Christians, it is claimed that Lucifer the telescope is looking for aliens. And that when they find these aliens, they will use them to take over the world in favour of Vatican rule.

There is even a book written on the matter – Exo-Vaticana: Petrus Romanus, Project L.U.C.I.F.E.R. and the Vatican's Astonishing Plan for the Arrival of an Alien Savior.
