Brother Guy Consolmagno visited the class in 2012, and presented his life story to the students: “Adventures of a Vatican Scientist.” He is Curator of Meteorites at the Vatican Observatory.
On the Colbert Report, Br. Consolmagno was asked if there is an Alien Jesus and whether the Vatican is looking for the shooting Star of David (you can skip ahead to 2:02 in this clip).
In 2009 George Coyne, Director Emeritus of the Vatican Observatory, spoke to students about “The Fertile Universe: A Theological and Philosophical Perspective.”
Gorge Coyne and Lynn Rothschild later participated in the Colloquia–The Dance of the Fertile Universe: Are we alone?
