City Star Party

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!

Perimeter Institute: Convergence (WEBCASTS)

There are moments in history when the right people converge at the right place, in the right time, to catalyze something entirely new. Convergence will be one of those moments. Physics is at a turning point. The most sophisticated experiments ever devised are decoding our universe with unprecedented clarity -- from the quantum to the cosmos -- and revealing a stunning simplicity that theory has yet to explain.

UofT Planetarium: Imagining the Size of the Universe

Showtimes: 7:00pm, 8:00pm, and 9:00pm There are many misconceptions about our universe, and the most common one is also the simplest – its size. Our universe is much bigger than we imagine it to be, and only through visual aid (such as a planetarium) can one really grasp the true dimensions of it. This planetarium show will journey through the different scales of the universe, starting with familiar objects like the moon and the Earth, and ending with the furthest reaches of the observable universe.

Beaches Library: Exoplanets and the Quest for Extraterrestrial Biology

Amaury Triaud, whose research has led to the confirmation of 48 new nearby exoplanetary systems, discusses how one finds a planet and the techniques that will soon tell us whether life forms have arisen on planets outside our solar system. What's Out There? Lectures in Astronomy presented in collaboration with the Dunlap Institute for Astronomy & Astrophysics.

New Moon

The moon is between us and the sun. Without the moon in the sky at night, deep sky objects are easier to observe.

Dark Sky Star Party

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, so the date and time are determined closer to.
