Join us this week if skies are clear!

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.

Video of the talks 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.

Join us as we celebrate International Astronomy Day with a fun-filled day – and night – of exciting programs and experiences for visitors of all ages.

Observe the stars via telescope with members of the Royal Astronomical Society of Canada. Witness the crescent Moon and Jupiter along with lively activities and demonstrations in this universally enlightening – and free – evening. In the event of inclement weather, Evening Star Party activities will proceed indoors in the Telus Conference Room.

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 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.

It is commonly believed that Mars is a cold, dry place. Due in large part to orbital imagery and robotic exploration of the Martian surface we can say without a doubt that Mars is indeed dry. The temperature on Mars is a bit more complex. As is the case with Earth, Mars experiences seasons and one would likely prefer to vacation near the tropics during winter. Temperature swings are much larger on Mars than on Earth. So while it may reach 20°C at noon near the equator during the Martian summer, by midnight it might plummet to -60°C.

Everyone is invited to join us and Durham Skies on May 19 for stargazing at the edge of Lake Ontario. Take a free look through different kinds of telescopes to get close-up views of craters on the Moon and spectacular Jupiter! Learn the names of the stars of spring and the constellation patterns they form. Peer deep into space and try your hand at spotting faint star clusters and nebulae. You can even bring your own telescope along and we'll give you advice on how to use it better.
