The Mars Opposition is our best opportunity to observe the Red Planet for the next several years. Join us at the David Dunlap Observatory to stage the next Martian Invasion of Richmond Hill.

This weekend tour introduces families to the wonders of astronomy through an indoor planetarium experience, craft activities for younger visitors and stargazing. Visitors will spend time in both the main building and observatory visiting the 1.88m (74") telescope, learning its history and getting to see celestial objects firsthand (weather permitting).

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 the Moon, the planets and more! Meet at the Chappell House Lawn. In case skies are not suitable for star-gazing on the scheduled date, the event will take place on Wednesday, June 20 at the same time.

What is the sound of a twinkling star? Can planets keep a beat? How loud was the big bang?

Showtimes: 7:00pm, 8:10pm, 9:15pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more!
