The International Year of Astronomy 2009 (IYA2009) was a global celebration of astronomy and its contributions to society and culture, stimulating worldwide interest not only in astronomy, but in science in general, with a particular slant towards young people. IYA2009 was an activity for the citizens of Planet Earth. It conveyed the excitement of personal discovery, the pleasure of sharing fundamental knowledge about the Universe and our place in it, and the value of scientific culture.
IYA2009 activities took place all over Canada — locally, regionally and nationally. Canada was proud to be among the 148 countries that participated in international activities, as well as having offered uniquely Canadian programs throughout the year.
On 7 Sept. 2010 the International Astronomical Union (IAU)’s IYA Secretariat released a final report. The report shows that at least 815 million people in 148 countries participated in the world’s largest science event in decades. How often Canadian activities and contributions are mentioned in the IAU report reflects the work of hundreds of volunteers in Canada.
