Symposium featuring gathering of Indigenous Knowledge Keepers, Elders, educators and scholars to share and exchange towards reclaiming, preserving, and revitalizing Star Knowledge with Indigenous communities worldwide.

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!

In a year filled with previously unimagined news, this announcement might have been the most surprising: Scientists have identified signs of possible life, not far out in the galaxy, but right next door, on Venus. Or rather, over Venus, in its clouds. Join our staff astronomer and ask your questions about Venus, phosphine and whether this news has more science fact or science fiction.

Happy Fall Equinox! We'll spend this session talking a bit about what equinoxes and solstices actually are, and will then jump into some lunar targets.

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. Check our homepage for GO/NO-GO calls as this event is weather dependent.

Join us at the Ontario Science Centre for our monthly Solar Observing on the TELUSCAPE.

The space science behind Hugo Award-winning science-fiction writer Robert J. Sawyer's new novel, The Oppenheimer Alternative.

We'll help you get started in visual astronomy by explaining the basics - how to use a sky chart, how sky coordinates work (spoiler alert - it's easy), what's a variable star, how to tell a galaxy from globular cluster, and more.

Mars and the Moon are getting close this week! Once you spot those in the next couple days, we'll be on the hunt for a little bit of everything, and a lot of double stars.

From the first announcement of its discovery in the atmosphere of Mars in 2003, methane has “punched above its weight” in our scientific imagination of the red planet. Because methane is quickly destroyed by the current chemistry active on Mars, it has to be supplied in the present day by some as yet unknown process. On the Earth, it is living systems that produce the abundant methane that we see in our atmosphere.
