Welcome to the Vatican City Portal

The flag of Vatican City

Vatican City (/ˈvætɪkənˈsɪti/ ), officially the Vatican City State (Italian: Stato della Città del Vaticano; Latin: Status Civitatis Vaticanae), is a landlocked sovereign country, city-state, microstate, and enclave surrounded by, and historically a part of, Rome, Italy. It became independent from Italy in 1929 with the Lateran Treaty, and is a distinct territory under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See, which is itself a sovereign entity under international law, maintaining the city-state's temporal power, governance, diplomatic, and spiritual independence. The Vatican is also a metonym for the pope, the city-state's and worldwide Catholic Church government Holy See, and Roman Curia. The country has the world's smallest land area and the smallest population, with 764 citizens as of 2023.

With an area of 49 hectares (121 acres) and as of 2023 a population of about 764, it is the smallest state in the world both by area and by population. It is also the second-least populated capital in the world. As governed by the Holy See, Vatican City State is an ecclesiastical or sacerdotal-monarchical state ruled by the Pope, who is the bishop of Rome and head of the Catholic Church. The highest state functionaries are all Catholic clergy of various origins. After the Avignon Papacy (1309–1377) the popes have mainly resided at the Apostolic Palace within what is now Vatican City, although at times residing instead in the Quirinal Palace in Rome or elsewhere.

VATT from ground level
The Vatican Advanced Technology Telescope, aka the VATT, is a 1.8 meter Gregorian telescope observing in the optical and infrared. It is part of the Mount Graham International Observatory. It is situated on Mount Graham in southeast Arizona, and it achieved 'first light', the first starlight to pass through the telescope onto a detector, in 1993. It is operated by the Vatican Observatory, one of the oldest astronomical research institutions in the world, in partnership with The University of Arizona.

The heart of the telescope is an f/1.0 honeycombed construction, borosilicate primary mirror. The mirror was manufactured at The University of Arizona's Steward Observatory Mirror Laboratory[1], which pioneered both the spin-casting and the stressed-lap polishing techniques which are being used for telescope mirrors that include the 6.5 meter aperture MMT and Magellan telescopes and the two 8.4 meter mirrors of the Large Binocular Telescope. The VATT's mirror is unusually 'fast', f/1, which means that its focal distance is equal to its diameter. Because it has such a short focal length, a Gregorian design could be employed which uses a concave secondary mirror at a point beyond the primary focus; this allows unusually sharp focusing across the field of view.

The unusual optical design and novel mirror fabrication techniques mean that both the primary and secondary mirrors are among the most exact surfaces ever made for a ground-based telescope. In addition, the skies above Mount Graham are among the most clear, steady, and dark in the continental North America. Seeing of better than one arc-second even without adaptive optics can be achieved on a regular basis.
