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.

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.

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.

Speaker: Nick Tacik Black holes are one of the most fascinating objects in the universe. From science fiction to the offices of astrophysicists, their mystery has captivated many. But what do we really know about them? Surprisingly, a whole lot! What happens when you fall into a black hole? What happens when two black holes collide? How do we know black holes really exist? What is a wormhole? Is spaghettification even a real word? In this talk, Nick Tacik will answer all these questions, and more, about the wondrous world of black holes.

Paul Delaney, York University The search for Pluto started in 1781 with the confirmed observation of Uranus. It took until 1930 for an astronomer to find the "9th planet."  Little did Clyde Tombaugh know the excitement his discovery would generate in the 21st century.  However, the secrets of the last of the "classical planets" would not be revealed until the fly by of the New Horizons spacecraft in July 2015.  This lecture will summarize the history of Pluto and the results sent back to date from New Horizons.  The revelations are unexpected!

Join the Dunlap Institute on the evening of Sunday, September 27, 2015 to watch the total lunar eclipse. You won’t get another chance to see this spectacular celestial phenomenon until 2019. Even better, this year’s eclipse is special because it’s taking place during a “supermoon”, when the Moon is about as close to Earth as it gets. During this time, the Moon will appear subtly larger than normal. This event is FREE but we request that guests RSVP on our Facebook Event Page.
