Considered the most influential discovery of the century, gravitational wave GW150914 broke records in physics, astronomy, and interferometry - with still more to come. Join CJ Woodford, PhD Candidate from the University of Toronto Dept. of Physics, as we discuss this incredible discovery, the future of gravitational wave astronomy, and the new field of multimessenger astronomy.

In this profusely-illustrated, non-technical presentation, you will learn how Toronto became a "centre of the universe" for astronomical research, education, and public outreach, in parallel with the development of our city and our country over the last two centuries.

Explore the biggest, fastest, brightest and most extreme things in the universe and check out a meteorite petting zoo! Presented by astronomer Tom Vassos.

This Fall and Winter, spend a Sunday afternoon in the OTHER dome at the DDO!

Speaker: Paul Delaney, University Professor, Senior Lecturer, Allan I. Carswell Chair for the Public Understanding of Astronomy, York University

Come see the planets as you've never seen them before! On September 14, join us for our second annual Planet Gazing Party with telescopes, prizes, stars and planets. Starting at 7:30pm, we'll have telescopes set up to view Jupiter, Saturn, and their moons. Come see mountains and craters on our own Moon in spectacular detail. Talk to astronomers and telescope enthusiasts and get all your space questions answered. Take a selfie with our gigantic Moon globe and play trivia games to win great prizes.

As the lazy days of summer fly past, planning is in full swing for our fall events. One of those events is the fall work party at the CAO. This year’s fall work party takes place a little earlier in the season on the weekend of September 13-15.

The Bentway brings the Moon under the Gardiner with a presentation of Museum of the Moon – a seven-metre wide touring sculptural work by UK artist Luke Jerram, which fuses lunar imagery to bring the moon’s surface to life on earth.

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.

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.

Durham Skies Astronomy and the RASC, Toronto Centre are donating a reflecting telescope to the Pickering Public Library at an unveiling ceremony at Millennium Square on Friday, September 6 at 7:00pm. Pickering Ward 1 Councillor Maurice Brenner, Pickering Library CEO Kathy Williams, Toronto Centre President Ralph Chou and Gary Wilkins of Durham Skies Astronomy will say a few words before the telescope is unveiled and aimed at the Moon for "first light." Since rain is not expected, the ceremony will be held at Millennium Square as originally planned.
