Jesuit priest Jose Gabriel Funes, director of the Vatican's astronomic observatory, says star-gazing brings him closer to God. "I became an astronomer in order to get closer to God who created the universe," said Funes at the observatory in the vast park surrounding the pope's summer residence in Castel Gandolfo, near Rome.
