Cosmic rays are the most energetic particles in the universe. Travelling at speeds mere fractions off from the speed of light, they accelerated in the remnants of dying stars and supermassive black holes. In this talk, we’ll talk about how cosmic rays interact with and influence their surroundings as the move throughout galaxies and intergalactic space along magnetic field lines.

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!

More than 99 percent of the visible matter in the universe is built from protons and neutrons and the nuclei that they form. This rich structure emerges dynamically from the complex interactions of quarks and gluons, the most elementary particles that have been discovered. Understanding how nuclear physics arises from the underlying quark and gluon dynamics is a computational challenge that pushes the capabilities of the world’s largest supercomputers.

Enter into a world where science, technology, engineering, art and math collide to create STEAM-Powered Stories. Take in and create new narratives through interactive experiences. You’ll quickly see the potential for STEAM to fuel creativity. STEAM-Powered Stories is a free event. During Nuit Blanche Toronto, select areas of the Ontario Science Centre are open to the public. Parking is $10 (member discount applies) before 12:00am, and parking is free after 12:00am. Food and beverages are available for purchase.

On Saturday September 29th from 7:00pm to 7:00am, experience the universe through new eyes and new ears with One Sky, a Nuit Blanche Toronto installation. This exhibition created by astrophysicist-musician Matt Russo and SYSTEM Sounds, and presented by the Dunlap Institute. With One Sky, you’ll enjoy a sunrise to sunset, multi-sensory experience of the celestial sphere.

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.

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!
