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.

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!

This Fall and Winter, spend a Sunday afternoon in the OTHER dome at the DDO!

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.

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.

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

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!

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?

Hover above the Moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy.

In his new book An Earthling's Guide to Outer Space, beloved science commentator Bob McDonald takes us on a tour of our galaxy, unraveling the mysteries of the universe and helping us navigate our place among the sta

Hey stargazers! Ever wonder how astronomers study the history of galaxies? If so, join ASX at our Star Talk on Wednesday, October 30, in Lash Miller Chemical Laboratories (LM), Room 161.

See the Milky Way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light polution, there is so much to see.

Families will be introduced to the wonders of astronomy through a presentation on a variety of exciting astronomy topics, followed by age-appropriate celestial activities and a demonstration of the 74" telescope.

Albert Einstein predicted a century ago the existence of gravitational waves – ripples in the fabric of spacetime moving at the speed of light.

Come view the 2019 Orionid Meteor Shower with the Allan I. Carswell Observatory Team at York University!
