The United Nations Generai Assembly 6801 Session proclaimed 2015 as the "lnternational Year of Light and Light-based Technologies. Light plays a fundamental role in sustaining lite on earth through photosynthesis. Studies and ongoing discoveries have shown how the many applications of light through medicine, communications, culture, and entertainment have revolutionized society. The intemational year will have a broad focus, not only on the scientific dimension, but also on the need to promote greater public knowledge and awareness on the way light-based technologies can sustain human development Numerous and varied events will take piace during the year with activities orga- nized at the regional, national and intemational levels. Other goals of the initiative include improving the quality of lite, promoting science careers for women, and education for young people. The Holy See takes an active role in contributing to the internation- al scientific community dedicated to the study of natural phenome- na and their effects and influence on society. The Vatican's historic telescopes at the papal summer residence of Castel Gandolfo, and its ultra-modem telescope in Tucson, Arizona, are a living testimony to this longstanding and ongoing commitment to scientific research. The commemorative stamp issued by Vatican City features a detail of a Sistine Chapel fresco by Michelangelo on the creation of the stars, an eternai symbol that ali comes from and returns to God the Creator. At the beginning of the Bible we read: "Then God said: Let there be light, and there was light. God saw that the light was good. God then separated the light from the darkness. God called the light 'day', and the darkness he called 'night'. Evening carne, and moming followed" (Genesis 1:3-5).
