When peering into the cosmos, astronomers can only gather instantaneous snapshots of celestial objects whose evolution — with rare exceptions — unfolds on timescales far too long to be probed within a human lifetime.

Family Nights are a great introduction to the night sky for our younger guests. Look through telescopes, make some space crafts, visit the Skylab and find out what's really up there! Family Nights require tickets to be purchased in advance. This program runs regardless of sky or weather conditions. If skies are clear you can check out the night sky through a variety of telescopes including the biggest optical telescope in Canada! The evening also includes a presentation in our special Skylab that offers great (virtual) night sky viewing.

Showtimes: 7:00pm, 8:00pm, and 9:00pm Often, when one thinks of the solar system, only the planets and the Sun come to mind. But what about all the other stuff? There are millions of asteroids in the asteroid belt, tens of millions of objects in the Kuiper belt, and probably trillions of objects in the Oort cloud, not to mention the hundreds of Moons and dozens of dwarf planets scattered throughout the solar system. In this show, we will explore the underdogs of the solar system: the asteroids, comets, moons, and dwarf planets who don’t get nearly enough respect!

The moon is between us and the sun. Without the moon in the sky at night, deep sky objects are easier to observe.

The Astronomy Club at York University and the York University Observatory present Toronto's very own Plutopalooza event, an event that is being held in cities across the world! Plutopalooza is a celebration of New Horizons' arrival at the Pluto system after its nine-year journey across the solar system. It will bring together astronomy and space exploration enthusiasts to share together their excitement for the spacecraft's arrival at this distant world.

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. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window, so the date and time are determined closer to.

Dr. Doug Welch, McMaster University Star Talk nights offer great talks by great speakers on astronomy, space science and sometimes, science fiction. You'll also have a chance to tour the Observatory and (weather permitting) check out the night sky through a variety of telescopes set up on the lawn and through the big scope in the Main Dome. If the weather gods are angry, you can check out the (virtual) night sky in our special Skylab.

This event is held if the previous event did not happen because of overcast skies.Join us at the Ontario Science Centre for our monthly Solar Observing on the TelusScape 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.

Start your own space program and reach to the stars! Kerbal Space Program is an award winning game that teaches players real-world physics and engineering skills as they attempt to explore the Kerbal solar system. Players assist the lovable-but-hapless Kerbals as they build rockets and carry out orbital missions. In the end players learn the difficulties NASA and ESA face when traveling to the stars. This multi day program will start out with a tutorial, and then attempt a mission to the moon or even another planet.

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. Talks start at 7:30 socializing starts at 7:00.
