The Heavens Declare the Glory of God, Notre Dame Retreat House, Canandaigua, NY

5-6 April 2024

A total eclipse of the sun is an awesome and unsettling sign in the heavens. Shadows of leaves double themselves on the ground, making us wonder about our vision. Night descends abruptly, though the sun is still high in the sky. Eclipses have much to tell scientists about how the universe works, from orbital mechanics to Einstein's theory of relativity. Likewise these events have something to say to us about creation and the Creator, for as St. John of Damascus said, "the whole earth is a living icon of the face of God." Join us as we explore some of the science that surrounds solar eclipses, and to reflect on what these signs in the sky might have to tell us about the glory of God.
