Dark Sky Star Party (GO for Monday)
See the Milky Way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light polution, there is so much to see. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window. Check our homepage for GO/NO-GO calls as this event is weather dependent.

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.

OSC Nuit Blanche: Evening Telescope Observing / Observe the Moon Night 2019
Have you ever looked through a telescope? Take a tour of the night sky through a telescope and snap a photo or two of your favourite celestial body. Learn about the phases of the Moon, get an up-close look at the planets, and gaze at the brightest stars (weather permitting).
It’s also International Observe the Moon Night. Contemplate the Earth indoors then head outdoors to consider the Moon, stars and neighbouring through a high-tech telescope.
