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.

This Fall and Winter, spend a Sunday afternoon in the OTHER dome at the DDO! Join us in the Starlab Digital Planetarium and take an interactive journey through the Universe, led by a DDO astronomer. Tour the night sky and see close-up views of galaxies, nebulas, and star clusters, view our Solar System's Planets and alien exo-planets, land on the moon, Mars - and the Sun, travel home to Earth from the edge of the Universe, hear Indigenous starlore, and watch immersive fulldome movies!

Join the Allan I. Carswell Observatory Team at York University in viewing Mercury transit the Sun!

NASA’s latest Mars mission touched down roughly a year ago. Tasked with detecting even the slightest tremor in the planet’s crust, tracking its weather 24.5 hours a day, and sensing its internal temperature, InSight is allowing us to explore Mars like never before. Let’s take a look at what InSight has shown us so far, and what it could reveal to us about our second favourite terrestrial planet.

Black holes are perhaps the strangest thing in a very strange universe. An almost unbelievable prediction of Einstein’s theory of General Relativity, black holes create a gravitational pull so strong, they can trap anything that gets too close. Even light. Black holes also pull on our imaginations, often appearing as the villains in science fiction. Join RCIScience for an exploration of the latest science about black holes and a discussion about how they are depicted in popular culture. Are black holes truly terrifying?
