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.

Join us at the Ontario Science Centre for Astronomy Week with a special event on Monday—a rare Transit of Mercury. We will be set up on the TELUSCAPE observing pad in front of the Science Centre's entrance with specialized telescopes that are safe to aim at the Sun. http://www.space.com/32476-mercury-transit-may-2016-rare-event.html In the event of inclement weather, a live stream of the event will be presented in the Gemini Room.

Here on earth, we can only see two planets pass between us and the Sun - and it doesn't happen every day! The last time we saw Mercury appear to glide across the face of the Sun was in 2006. The next time it happens is 2019. Join us for this special daytime event at the David Dunlap Observatory. The gates will open at 10:00 a.m. If the weather's clear, stop by for a (safe) peek at the Sun through a variety of solar telescopes. We'll be webcasting too! For obvious reasons, the big telescope will not be in use. There's no charge. Just drop by.

Join us this week if skies are clear!

It's AstroNuts' annual kids' space club fundraiser!

Join Sara Mazrouei as she discusses our Moon and how its history is linked to the Earth’s distant past.

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.
