Everyone is invited to join us and Durham Skies 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, and planets visible in the current night sky. Peer into deep 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.

Fourteen billion years ago, the universe was little more than a cloud of hot hydrogen gas. Patrick Breysse will tell the story of how that cloud of gas evolved into all of the galaxies, stars, and planets we see around us today. In the process, he'll explain some of how astronomers study the history of the universe, and how telescopes are secretly time machines that let us look directly into the distant past. He'll also talk about some of the great mysteries that remain in this story, and how we're working in Toronto and elsewhere to solve them.

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. Check our homepage for GO/NO-GO calls as this event is weather dependent.

Celebrate the 50th anniversary of the lunar landing with live music, dancing, art, a food fair, and an artisan market! At 10:56 pm on July 20, 1969, humans first set foot on the Moon, expanding the limits of humanity. Now to celebrate 50 years since that milestone, we’re hosting a two-day festival, featuring live music, a food fair, artisan market, and family-friendly activities. Join us for a weekend full of lunar-inspired fun!

Visit a unique historical site in Richmond Hill and experience an engaging presentation led by expert and researchers in astronomy, covering a variety of exciting astronomy topics. After the presentation, participants will tour the observatory and see a demonstration of the 74" telescope. If the sky is clear, the dome will be opened and the telescope pointed to an interesting celestial object for the visitors to view. Please wear/bring appropriate supplies for being outdoors. All registered participants under the ages of 16 must be accompanied by a registered adult.

Join us at the Ontario Science Centre for our monthly Solar Observing on the TELUSCAPE observing pad. This is the area in front of the Science Centre's entrance. We use specialized telescopes that are safe to aim at the Sun. Check our home page on the Friday prior for GO/NO-GO calls as this event is weather dependent.

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!
