Everyone is invited to join us and Durham Skies this May 14 for stargazing at the edge of Lake Ontario. Take a free look through different kinds of telescopes to get close-up looks at craters on the Moon, brilliant Mars, magnificent Jupiter with its moons, and the spectacular rings of Saturn. Learn the names of springtime stars and the constellation patterns they form. Peer deep into space and try your hand at spotting spot faint star clusters and nebulae.

Celebrate International Astronomy Day with telescope observing, activities, crafts, and ‘Science Slam’ presentations by astronomers about strange, unbelievable, and mind-blowing discoveries in space.

Cloudy or clear, join us for programs including presentations in our Skylab and space-themed arts & crafts (Space Crafts!) and tours of the big telescope.

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!

Join us for our monthly recreational astronomy night meeting. This is where our members get to show their latest projects, or give tutorials and tips on just about everything to do with Astronomy. Talks start at 7:30, socializing starts at 7:00. • Ron Macnaughton - How David Thompson Did It. Celestial Navigation Around 1790• Jim Chung - How to make your own cooled DSLR for less than $200!• Michael Watson - 2016’s Celestial Rarity: Mercury crosses the Sun

UPDATE: 2016-05-26 Thanks to all the members who have volunteered for the Spring Work Party at the CAO. We are happy to report on the overwhelming offers to help from our membership and now the house is completely filled up (with overflow people camping as well), so we cannot accept any additional volunteers for this work party. Please keep an eye out for an announcement about a Star-B-Que to be held at the CAO in July, and mark your calendars for the Fall Work Party which is currently scheduled for the weekend of October 14 - 16, 2016

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.

Join us at the Ontario Science Centre for our monthly 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. Check our home page on the Friday prior for go/no-go calls as this event is weather dependent.
