Radio telescopes — such as the Canadian Hydrogen Intensity Mapping Experiment (CHIME), HIRAX, and the planned CHORD — will lead to unprecedented advances in astronomy. How will they shape future research? To find out more, join us online on Wednesday, October 28 at 6:00pm.

Have you ever looked through a telescope? Take a tour of the night sky through a telescope and snap a photo or two of your favourite celestial body. Learn about the phases of the Moon, get an up-close look at the planets, and gaze at the brightest stars (weather permitting).

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.

What’s the biggest constellation out there, and the smallest? What's the farthest thing a human eye can see - or the hottest star - or the closest star cluster?

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!

We're catching a few last targets and going over some previous ones that you may have missed from earlier in this series. We're going to do our best to see the Zodiacal Light this week too.

Mars is at opposition tonight! That means it's on the exact opposite side of the sky to the Sun, and we get to see it all night long. Join us tonight for live views of Mars and the other fall planets through our members' telescopes. We'll have a guest expert on Mars and will be spending lots of time answering your pressing questions about the red planet!

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.
