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.

HAA welcomes Trevor Jones as our guest speaker for our first meeting at McMaster Innovation Park, our new home.

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!
