Learn all about being an amateur astronomer and join in on hands-on activities at this special weekend Father’s Day Family Astronomy activity fair.

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!

Come view Jupiter at Opposition with the Allan I. Carswell Observatory Team at York University! At Opposition, Jupiter will be bigger and brighter than ever in 2019, making this the best time of the year to view Jupiter and its moons! Admission is free, and there will be multiple telescopes available for viewing! While the event is planned to take place on June 10th, if bad weather occurs we have a rain date of June 11th. Updates regarding this will be posted by 4:00pm on social media.

The Origins Institute in partnership with the McMaster Alumni Association is pleased to welcome to Hamilton, Dr. Sarah M Hörst from Johns Hopkins University, to give a FREE public lecture on Titan: Ingredients for Life.

Join University of Toronto's Dr. Bryan Gaensler as he chats about the wonders of the Universe.

In this profusely-illustrated, non-technical presentation, you will learn how Toronto became a "centre of the universe" for astronomical research, education, and public outreach, in parallel with the development of our city and our country over the last two centuries.

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.

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.
