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.

Our most recent generation of cosmology experiments, such as the Planck satellite and observations of distant supernovae, have reduced all of cosmology to the very precise measurement of eight parameters. This relatively simple model seems complete with no hints of additional elements required to explain the entire evolution of the Universe from the Big Bang to some far distant future. 

Enjoy and learn about the night sky through an engaging presentation delivered by an astronomer. Learn about history, mythology and how to identify star constellations overhead. This is a family-friendly event.

Hello astrophiles! Star Trek, Star Wars, and basically all space-based sci-fi are stuffed full of exotic extraterrestrials and peculiar planets. But what is the scientific basis of these weird and wonderful worlds? To find out, come out to ASX's November Star Talk on Wednesday, November 21st, in McLennan Physical Laboratories (MP), Room 102 where Dunlap Institute Director Prof. Bryan Gaensler will be shedding light on the hard facts underpinning science fiction!

Join the Hamilton Amateur Astronomers this November 16 for their Fall telescope clinic.

Generator is back! Chris Hadfield’s famed comedy, music and ideas extravaganza is returning to Roy Thomson Hall. Past years saw Neil Gaiman and Amanda Palmer, Mythbuster Adam Savage, Destin Sandlin from Smarter Every Day, architect Moshe Safdie, poets, cyborgs, exoskeletons, bionic Ironman hands for children, and much, much more. It isn’t an easy show to describe – you just have to experience it to understand.

In this profusely-illustrated, non-technical presentation, you will see the universe, as revealed by astronomy, is just as exciting as the universe of science fiction and video games - and it's real! And you can see it, study it, and understand it! Presented by Dr. John Percy, who is Professor Emeritus at the University of Toronto, in Astronomy & Astrophysics, and in Science Education. Followed by questions and discussion.

Come view the 2018 Leonid Meteor Shower with the Allan I. Carswell Observatory Team at York University! With up to 15 meteors visible every hour, multiple telescopes available for viewing celestial objects and a constellation tour, it will be a fun, astronomy filled night! Weather updates will be posted by 4:00pm on social media. Hope to see you there!

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!
