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.

Showtimes: 7:00pm, 8:15pm 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!

Babak Tafreshi is the founder of The World at Night (TWAN) program, a science journalist, and National Geographic photographer taking images that merge art, culture, and science by bridging Earth & sky. His work reconnects people with the night sky and the values of natural nights. For his global contribution in this field he received the 2009 Lennart Nilsson Award, the world’s most recognized award for scientific photography at the time. @babaktafreshi | babaktafreshi.com

The recent discovery of gravitational waves marks the dawn of a new field of astronomy and provides new opportunities to study several elusive systems in the Cosmos. Compact binaries, made up of pairs of stellar remnants, are difficult to observe with traditional astronomical observations, but they are the most prolific source of gravitational waves. In this talk, Dr. Katie Breivik will give an overview of gravitational-wave astronomy and the exciting astrophysics we have uncovered from the 11 gravitational-wave detections to date.

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