Pluto has always been the favourite of many who have cast their thoughts out to the stars and planets. More than that though, it has played a key role in our understanding of how our solar system is formed and it may be the key to further exploration of our neighbourhood of space. In this richly illustrated presentation we explore its history, our recent discoveries and how it may lead us to one of the greatest astronomical discoveries of the 21st century.

Fossils show us that millions of years ago giant reptiles roamed the Earth. Yet, where are they now?

Showtimes: 7:00pm, 8:00pm, and 9:00pm In 1977 two small probes, Voyager 1 and 2, were launched from Earth with a mission to study the outer solar system. Both spacecraft visited Jupiter and Saturn, and Voyager 2 passed by Uranus and Neptune, returning images to Earth which allowed us to make surprising discoveries about these distant planets. Now these probes are entering interstellar space, making them the furthest man-made objects from the Earth!

Have you ever wondered whether we're alone in the cosmos? For thousands of years, we have only been able to speculate. Now, astronomers searching for planets capable of supporting life are making daily progress toward answering this incredibly compelling question. Join me for a non-technical explanation of the science behind the search for Earth-like planets and a summary of the latest results. Presented by: Dr. Michael Reid - Associate Professor of Astronomy from the University of Toronto.

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.

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.

We’ve all heard about ground-based telescopes and space telescopes, but what about telescopes that are flown on balloons? What do they do? How do they work? Why do we use them? In this lecture, Rachel Domagalski will talk about the history of balloon astronomy, as well as some of the science that’s come from balloon telescopes. She will also talk about the development of two very different balloon telescopes, SPIDER and SuperBIT, that’s taking place right here in Toronto.

The stars of the night sky appear gentle, peaceful and unchanging. But this is a lie. The Universe is a violent and catastrophic place, with dozens of tools at its disposal to wipe out all life on Earth with almost no warning. Astronomers are still only beginning to appreciate the true scope of the dramatic forces that drive the Universe's evolution.

Earthshine Astronomy and Space Science Organization and The Riverwood Conservancy (TRC) present this four night course open to budding astronomers ages 12 and up. The course is taught by members of the Royal Astronomical Society of Canada – Mississauga Centre. If the sky is clear, there will be observing for 30 minutes after the end of the session.
