The Royal Astronomical Society of Canada

The Royal Astronomical Society of Canada (RASC) is one of Canada’s oldest scientific organizations and a leading voice for astronomy education and outreach. Founded in 1868 and granted its Royal Charter in 1903, the Society has played a significant role in promoting the study and appreciation of astronomy, space science, and related fields across the country. Its membership includes professional astronomers, educators, students, and enthusiastic amateur observers who share a common interest in exploring the universe.

RASC is organized into local centres located in cities and regions throughout Canada, as well as international branches. These centres host public lectures, observing nights, star parties, workshops, and educational programs designed to make astronomy accessible to people of all ages and backgrounds. The Society is also well known for its publications, including the Observer’s Handbook, an internationally respected annual reference for astronomers, and SkyNews magazine, which highlights current discoveries and observing tips.

Beyond education and observation, the Royal Astronomical Society of Canada is active in advocacy for dark-sky preservation and science literacy. Through initiatives such as dark-sky reserves and public outreach campaigns, RASC works to protect the night sky from light pollution and to inspire curiosity about the cosmos. By connecting communities with the wonders of the universe, the Society continues to foster a strong culture of astronomical learning and discovery in Canada and beyond.
