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.

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.
