Speakers: Randy Attwood, Mississauga Centre Honourary President; Michael Watson, Toronto Centre The solar eclipse of August 21, 2017 presents an opportunity for many amateurs to observer their first total solar eclipse. These are rare events and may be overwhelming for the novice TSE observer. The presenters have seen several dozen eclipses and will share their experiences with advice to those planning to travel to the centre line.

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!

Showtimes: 7:00pm and 8:00pm

The day after the anniversary of the first human in space (often called Yuri’s Night after the Russian who accomplished the feat) you might be suffering from a bit of space withdrawal sickness. Have no fear – The Planetary Society and STEAMLabs are teaming up to give you another dose of space by putting you at the controls!

Join us in the Youth Hub as Prof. McCall from York University talks about what caused the extinction of dinosaurs and what could happen to us in the future.

Prof. Harald Pfeiffer, Canadian Institute for Theoretical Astrophysics Video of the talk

Learn about how the AAVSO coordinates, evaluates, compiles, processes, publishes, and disseminates variable star observations to the astronomical community throughout the world, and other topics on variable star observation and how it contributes to astrophysics.

In Toronto, the Commercial Space Blog will be sponsoring a Yuri's Night Party at the Polish Combatants' Hall.

Join Professor Emeritus John Percy for a look at how Toronto has become a world centre for astronomy research, education, and public outreach, in parallel with the development of our country, our city, and the University of Toronto.

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.

This talk will focus on the past, present, and future of big data in astronomy.
