Millennium Square Stargazing (first clear night: Friday or Saturday) (CANCELLED)

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.

Perimeter Institute: Music of the universe: Gabriela González public lecture webcast

Albert Einstein predicted a century ago the existence of gravitational waves – ripples in the fabric of spacetime moving at the speed of light. It was believed that these ripples were so faint that no experiment would ever be precise enough to detect them. But in September 2015, LIGO did exactly that. The teams working with the Laser Interferometer Gravitational-wave Observatory (LIGO) detectors in Louisiana and Washington measured a loud gravitational wave signal as it traveled through the Earth after a billion-year journey from the violent merger of two black holes.
