Since the discovery of the first exoplanets in the early 1990s, we have detected more than 4,000 worlds beyond our solar system. Many of these are similar in size to our Earth, leading to an obvious question: could any be habitable? For now, we typically only know the size and orbit of these planets, but nothing about their surface conditions. Although we cannot know for sure if these worlds could support life, we can use models to speculate on what we might find there.

Join us for the November AstroTour! Victor Chan, a PhD candidate at the University of Toronto's Department of Astronomy and Astrophysics, will be sharing his expertise on cosmology!

For the first time since 2016, the planet Mercury will pass between the Earth and the Sun, making it visible as a small dot against the Sun’s disc. While it will be an amazing sight to behold, looking directly at the sun is dangerous. So the experts from the Mississauga Centre of the Royal Astronomical Society of Canada will be setting up their properly-filtered telescopes at Riverwood to offer you safe, clear views of the transit.
