Let's explore High Park's amazing and mysterious bat populations and the astronomical wonders above us with the help of our telescope!

Astronomy Booth: Small Bodies in the Solar System

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.

Join the Allan I. Carswell Observatory Team at York University in viewing Mercury transit the Sun! Come use solar telescopes to watch as Mercury passes in front of the Sun for the first time since 2016! Admission is free, and Mercury won't transit the Sun again until 2032, so make sure you don't miss it!

Magnetism is one of the fundamental forces of nature and shows up in many places in our daily lives, but it’s not something that most people associate with astronomy. Yet the entire universe is filled with magnetic fields on all scales: from planets to stars to galaxies to galaxy clusters and beyond. In this talk we will take a look at the magnetic universe: the nature of magnetism, the causes of magnetism in astronomical objects, how we detect magnetism in distant places, and how magnetic fields affect our understanding of astrophysics.

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.

Everyone is invited to join us and Durham Skies for stargazing at the edge of Lake Ontario. Take a free look through different kinds of telescopes (including solar-filtered scopes) to get close-up looks at sunspots, craters on the Moon, and planets visible in the current night sky. Peer into deep 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 expert advice on how to use it better.
