Join us online to learn basic astronomy that you can do on your own from your backyard! We'll explain the dance of the inner planets in the evening sky, talk about conjunctions, elongations, and transits, and share some tips for safely viewing the inner planets. Galileo did it - so you can, too!

Safely observe the sun with us, from the comfort of your home! During these family-friendly sessions, a DDO Astronomer will answer your questions about our closest star: the sun!

Join us for our monthly recreational astronomy night meeting. This is where our members get to show their latest projects or give tutorials and tips on just about everything to do with astronomy.

Arnold Brody takes his turn at showing us the celestial highlights for the month of April and doesn't miss a chance to remind us about the Millennium Square Public Stargazing Event on April 28 that he is organizing. Arnold is a member of the Royal Astronomical Society of Canada - Toronto Centre and gave his presentation to the Recreational Astronomy Night Hybrid meeting held April 5, 2023 at the Ontario Science Centre.

Each year on the last Saturday of March, we at AstroTours honour Earth Hour and hope to bring awareness to issues impacting our planet. This year is no exception! Join us on March 25 for an evening of short talks and a Q&A panel with three scientists at the forefront of environmental research. Speakers: - Devon Gray, member of the Hydrometallurgy group at Hatch

Star formation is incredibly inefficient. Compared to the available amount of gas in molecular clouds, only a few percent of the cloud forms stars. In this talk, I will talk about how dust is created, grows, and destroyed in the interstellar medium (ISM). Understanding the size and evolution of dust grains in ISM is significant in answering why star formation is a very inefficient process in the universe.

The Solar System with all its planets, moons, and asteroids are all around us -- even in your own home!

Join us online to learn basic astronomy that you can do on your own from your backyard! In honour of March Break and better weather, we'll look at the best sights to see in the late winter / early spring evening sky using a backyard telescope, binoculars, or just your eyes.

This March Break, learn about the sun and practice safe solar observing!

This March Break, join the David Dunlap Observatory to explore some of the dynamic action of space through comets, craters, and more!
