This weekend tour introduces families to the wonders of astronomy through an indoor planetarium experience, craft activities for younger visitors and stargazing. Visitors will spend time in both the main building and observatory visiting the 1.88m (74") telescope, learning its history and getting to see celestial objects firsthand (weather permitting).

Everyone is invited to join us and Durham Skies on July 21 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, rosy Mars, giant Jupiter, and Saturn with its rings. Peer deep into space and try your hand at spotting faint star clusters and nebulae. You can even bring your own telescope along and we'll give you expert advice on how to use it better.

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.

The red planet and the ringed gas giant are waiting for you among the stars. In celebration of World Space Week, observe Mars and Saturn* up close through a telescope. Launch a bottle rocket. Meet a real-life rocket scientist. Enjoy a special screening of the Journey To Space IMAX® film. World Space Week celebrates scientists and space explorers from around the globe whose work has helped humankind. This year, the theme is “Space Unites The World.”

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!
