Mars is at opposition tonight! That means it's on the exact opposite side of the sky to the Sun, and we get to see it all night long. Join us tonight for live views of Mars and the other fall planets through our members' telescopes. We'll have a guest expert on Mars and will be spending lots of time answering your pressing questions about the red planet!

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.

Today’s the day! Mars is at its closest approach to Earth, making it the biggest and brightest it will be for another 15 years!

In elegant and humorous prose which makes her book highly engaging and readable, theoretical astrophysicist, Dr Katie Mack, makes clear almost immediately where her story will end: with the end. Of Everything. It’s not a plot twist that’s wholly unexpected, but there’s more: fire. That’s going to be the element that is finally our grand undoing (the “we” is rhetorical - human life will long have been extinguished), white hot fire from the swollen sun like nothing we can imagine.

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

It's a great week for some planetary observing! Mars is at opposition, which means it'll be big and bright and beautiful as we come between it and the Sun.
