Consolmagno, who has a prodigious white beard, wavy gray bangs, and dark, beetling eyebrows, is one of fifteen scientists who currently make up the scholarly staff of the Vatican Observatory—all Jesuits and, inevitably, all men. (Their meals, perhaps equally inevitably, are prepared by a local woman.) At any given moment, about half of the fraternity is in Castel Gandolfo, which has been the institution’s home since the nineteen-thirties—although, for the past fifteen-odd years, the staff’s living quarters have been situated in a former convent a short distance from the palace. The other half of the team is in Arizona, a state that offers a remote mountain environment more conducive to astronomical observation than the light-polluted suburbs of Rome do. In the early nineties, at the Mt. Graham International Observatory, near Tucson, the Vatican installed a powerful four-million-dollar telescope and an astrophysics facility, together known as the Vatican Advanced Technology Telescope, or VATT. Consolmagno, like many of his colleagues, shuttles frequently between Italy and Arizona, rarely spending more than a few months in one place.journey-inline-newsletterinline-newsletter
