A Revolution in Astronomy: The Vatican Observatory and Spectral Lines
Venue, date and time

Biggar Kirk, Biggar
Late teens and adults
Father Christopher Corbally, a Jesuit astronomer with the Vatican Observatory, will describe how some 160 years ago, his fellow Jesuit, Father Angelo Secchi, began to look at the spectra (colours) of stars and probe their secrets. What were just pinpoints of light in the night sky became the focus of astrophysics. We will discover something of the elements in stars’ atmospheres, their sizes, and their ages. All this will be presented through the story of Secchi’s life, his faith, his multi-sided science, and his heritage, continued today through the Vatican Observatory.
