City Star Party (GO for Tuesday)

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!

UofT AstroTour: Sensing Hidden Signals with Pulsars

Pulsars, born after the splendid explosion of massive stars, are the most compact objects in the visible universe. Sitting on Earth, we receive regular pulses of light from pulsars. The accuracy of the period between pulses can sometimes rival that of an atomic clock. Pulsar studies have won two Nobel prizes: one for their discovery, and one for the first indirect evidence of gravitational waves. In this talk, Dongzi Li will explain how the compact nature and the excellent periodicity of pulses help make previously difficult studies feasible.

Dark Sky Star Party (NO GO)

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.

DDO Astronomy Family Night (WAITLIST)

Families will be introduced to the wonders of astronomy through a presentation on a variety of exciting astronomy topics, followed by age-appropriate celestial activities and a demonstration of the 74" telescope. If the sky is clear the dome will be opened and the telescope pointed to an interesting celestial object for the visitors to view. All participating family members must be registered and any participants under the age of 16 must be accompanied by a registered adult.

UofT Planetarium: The Life and Death of Stars (SOLD OUT)

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!
