Br. Guy Consolmagno calls himself a 'Sputnik Kid'. He started school the year the Russians launched the world's first satellite. Growing up in Detroit during the space race he remembers the excitement he felt watching Nasa launch rockets into space, "I grew up at a time when anything was possible." He was always fascinated with astronomy. In fact, his father always wanted to be an astronomer but could never turn it into a career. He would show Guy the stars at night and point out the different constellations. Little did he know back then that his son would not only go on to be an astronomer, lecturing at the prestigious colleges of Havard and MIT, but he would go on to become the director of one of the oldest observatories in the world - The Vatican Observatory.

The Vatican Observatory has been gazing at the stars since 1582. The church started the observatory to study the heavens in order to make changes to the church calendar. Over the years it became a way for the church to marry science and faith and explore the points where they intersect. The first telescopes were placed right on top of the Vatican, but as Rome grew bigger and brighter, the view of the stars started to fade and so in the 1930s the Vatican built a new large telescope at the Pope's summer residence at Castel Gandolfo 25km south of Rome, and also one in Arizona in the US!

There are twelve astronomers working at the Vatican observatory, but Br. Guy, the director, is unique as he is the only one who was appointed by a pope and saint, Saint Pope John Paul II. He worked under JPII, Pope Benedict, and now Pope Francis. He still wears his MIT ring, as well as his white priest's collar.

For this Heart and Soul special on the BBC World Service, we will visit the Vatican Observatory to hear about its fascinating history and meet the 'Sputnik Kid' who is passionate about showing the world that science and faith are not as opposed as you might think.
