Join Kevin Salwach as he counts down his list of the 10 Most Influential People in space history – the scientists, engineers, politicians, and of course the astronauts themselves, whose efforts have resulted in the success of humanity’s journey from home to explore the cosmos.

Showtimes: 7:00pm and 8:10pm

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!

Explore the universe with members of the Royal Astronomical Society of Canada. Telescopes will be set up to give you amazing views of our Moon, the planets and more!

Prof. Cheryl Bartlett was co-developer of "Integrative Science" and of "Two-Eyed Seeing," and was one of the organizers of International Year of Astronomy in Canada. In this sesquicentennial year, when Aboriginal culture and education require our attention, her work is of special interest.

Solar System Social is a space-themed speaker series that brings exciting ideas and research from the field of planetary science to the general public in form of short, informative, and interesting talks that last about 15 minutes each. This event focuses on asteroids and meteorites.

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.

Everyone is invited to join us and Durham Skies on June 2 for stargazing at the edge of Lake Ontario. Take a free look through different kinds of telescopes to get close-up views of craters on the Moon and spectacular Jupiter! Learn the names of the stars of spring and the constellation patterns they form. 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 advice on how to use it better.

Thirty years ago, the world was dazzled by the discovery of the fiery explosion of a dying star, called Supernova 1987A. This supernova was the brightest observed since the invention of the telescope 400 years ago, and the explosion and remnant has been actively studied ever since.

Spend the afternoon with Dr. Jennifer West, Postdoctoral Fellow at the Dunlap Institute for Astronomy and Astrophysics in the University of Toronto. Dr. West will speak about the importance of preserving dark skies and dark sky preserves.

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.

It’s that time of year again…..time to get the Carr Astronomical Observatory (CAO) ready for another season of observing for our members. This year’s Spring Work Party will take place May 27-28, 2017 - this is the weekend after the Victoria Day weekend. We do not have any major projects planned - just the normal season opening activities and many small jobs.
