In 1986 we organized the first Vatican Observatory Summer School in Astronomy and Astrophysics, and this has now become a biennial event in the Observatory's programs. For one month 25 young scholars, at least one-third from non-industrialized countries, are invited to Castel Gandolfo to study selected topics under a renowned faculty of senior scholars. All participants are granted partial support by the Vatican, and those from developing countries receive a further scholarship covering at least 75% of their travel and living costs.

Two International Symposiums, in 1998 and in 2002, have brought alumni from the previous Summer Schools together.
