The fact that the winter solstice occurs exactly today, 21 December, and at this very time, offers me the opportunity to greet all those who will be taking part in various capacities in the initiatives for the World Year of Astronomy, 2009, established on the fourth centenary of Galileo Galilei's first observations by telescope. Among my Predecessors of venerable memory there were some who studied this science, such as Sylvester II who taught it, Gregory XIII to whom we owe our calendar, and St Pius X who knew how to build sundials. If the heavens, according to the Psalmist's beautiful words, "are telling the glory of God" (Ps. 19:1), the laws of nature which over the course of centuries many men and women of science have enabled us to understand better are a great incentive to contemplate the works of the Lord with gratitude.In light of this event, it might make an interesting essay to have students explore the Galileo controversy, the mistakes the church made, and how they can be avoided in our time. One good DVD on the topic: Galileo's Battle for the Heavens.
