The Royal Astronomical Society of Canada (RASC) began as the Toronto Astronomical Club on December 1, 1868. The eight men who gathered to share their interest were not professional astronomers, just working-class citizens with a passion for astronomy.
More than 150 years later, the RASC continues to serve Canadians with a passion for astronomy. With more than 5,000 members and 29 centres across the country, the organization supports anyone who wants to learn more about the universe.
Attend a Star Party, visit a Dark Sky Preserve, learn about astrophotography, search for comets or prepare for the next eclipse. RASC centres host free public astronomy activities and our volunteers willingly share their knowledge with newcomers.
Become a member, and you’ll receive additional benefits, including our Observer’s Handbook, Journal, and invitations to events. The RASC wants everyone to enjoy astronomy.
Founded in 1868, The Royal Astronomical Society of Canada is Canada’s leading astronomy organization, bringing together over 5,000 enthusiastic amateurs, educators, and professionals. In addition to many national services, our 29 Centres offer local programs across Canada.
