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.

As the lazy days of summer fly past, planning is in full swing for our fall events. One of those events is the fall work party at the CAO. This year’s fall work party takes place a little earlier in the season on the weekend of September 13-15.

This Fall and Winter, spend a Sunday afternoon in the OTHER dome at the DDO!

Join us at the Ontario Science Centre this week for solar observing on the TELUSCAPE observing pad. This is the area in front of the Science Centre's entrance. We use specialized telescopes that are safe to aim at the Sun. We will be set up from Monday to Saturday from 10:00am-12:00pm daily. Check our home page for go/no-go calls as this event is weather dependent.

Celebrate International Astronomy Day at the Ontario Science Centre!

Let’s Celebrate International Astronomy Day!

We are a go for Friday. Please remember to dress warmly. Note also that the sky may be cloudy to start with but should clear around 9:00pm.

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.
