Speaker: Max King, University of Toronto In July 2015, the New Horizons spacecraft flew past Pluto, photographing the last unexplored major body in our solar system. Taking over 25 years from its original conception to its phenomenal photographic fly-by, New Horizons upended the space industry. We will explore the story behind the most unlikely expedition into our solar system, the development of the mission from scrap paper to the spacecraft itself.

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!

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!

Have you ever looked through a telescope? Take a tour of the night sky through a telescope and snap a photo or two of your favourite celestial body. Learn about the phases of the Moon, get an up-close look at the planets, and gaze at the brightest stars (weather permitting).

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.

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

Speaker: Randy Attwood, FRASC, Mississauga Centre

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!
