Explore the universe with members of the Royal Astronomical Society of Canada. Telescopes will be set up to provide amazing views of the Moon, the planets and more! Meet at the Chappell House Lawn.

What is the sound of a twinkling star? Can planets keep a beat? How loud was the big bang?

Everyone is invited to join us and Durham Skies on May 18 for stargazing at the edge of Lake Ontario. Take a free look through different kinds of telescopes (including solar-filtered scopes) to get close-up looks at sunspots, craters on the Moon, brilliant Venus and Jupiter.

See the milky way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light polution, there is so much to see. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window, so the date and time are determined closer to.

Finding compelling evidence for life on another planet would undoubtably be one of the biggest discoveries in the history of the human race. There are many places to look for such biosignatures, both in the Solar System and beyond. From the human perspective, the most exciting place is an Earth-twin around a Sun-like star. Chances are good for finding such a planet within the next few years. However, learning anything other than the planet's existence and its most fundamental properties such as mass and radius will be extremely difficult.

What can we learn from a group of stars that were born at the same time?

Have you ever looked up at the starry sky and felt small and insignificant compared to the vastness of the cosmos?

Showtimes: 7:00pm, 8:10pm, 9:15pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more!

2018 marks 150 years of lasting organized astronomy in Canada, and that story is pre-eminently the story of the RASC. Join us on the afternoon of May 12th for an open house launching the official opening of our new Archives space! This invitation is extended to all RASC members and their guests. The refurbished Archives facility is a RASC sesquicentennial project, providing improved storage, display, and consultation space for the RASC’s material heritage, and a congenial location for select meetings and programming, in a setting richly evocative of our history.

Science Rendezvous is a free annual all-day festival that brings science out of the lab and onto the street with the ultimate goal of improving student enrolment as well as public involvement in the science, technology, engineering, and mathematics (S.T.E.M.) fields.

A walking tour which describes how Toronto became a "centre of the universe" for astronomical research, education, and public outreach, in parallel with the growth of our city and country. An introduction to the people, organizations (including RASC), and institutions which have nurtured astronomy in Toronto. Ends up at Science Rendezvous!

Every year the Faculty of Science at York University joins forces with Main Street Markham to present Science Rendezvous at the award-winning Markham Farmers’ Market.
