The best kind of trivia is astronomy trivia!

Explore the universe with members of the Royal Astronomical Society of Canada. Telescopes will be set up to provide stellar views of the Moon, the planets and more.

The little constellation of Delphinus, the Dolphin, swims the autumn evening sky. It is easy to identify with unaided eyes, can be explored in binoculars, and has many interesting stars and deep sky targets for telescopes of any size.

The Toronto Centre is participating once again at the hugely popular (and entertaining!) Pumpkinville festival run by the Town of Ajax at beautiful Greenwood Conservation Area. In addition to our information tent, we will set-up solar telescopes. The Sun is quite active now, so we're sure to have sunspots to examine up close!! Visit Ajax's website for more details about the festival and free shuttlebus service.

Take a guided tour of the invisible universe on Dark Matter Night. In a hybrid event (in-person and live webcast) on October 26, dark matter researchers Katie Mack and Ken Clark will share insights into the ubiquitous, mysterious matter that makes up the majority of stuff in our universe.

Speaker: Dr. John Percy, University of Toronto
