Dark Sky Star Party (GO for Tuesday)

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.

Northern District Library: Cosmic Origins of Everyday Life

Our life on Earth, and the Earth itself, are products of cosmic events that happened long ago and far away, but are still on display in the night sky. How are the ingredients of life and the environments for life being made? Is the Earth special or typical? Is our Universe especially good at making life? Who else might be circling one of the stars in our sky?

ASX Star Talk: Planets Around Expired Stars

Professor Yanqin Wu investigates the formation and evolution of planets, both inside and outside our own Solar System. Her current attention is devoted to a recently discovered puzzle, the presence of planetary systems around white dwarf stars, stars that have lived through their lives and are cooling off quietly in their cemeteries. The observational evidence is difficult to square with our current knowledge about the extra-solar planetary systems, and perhaps a new picture is required.

Jane/Dundas Library: Archaeoastronomy: Astronomy of Civilizations Past

Runnymede Library: Planet 9 from Outer Space!?

In January of 2016, astronomers presented evidence that a giant planet may be lurking far beyond Neptune, quietly waiting to be found. If it exists, 'Planet 9' would be the first solar system planet to be discovered in over 170 years, with all due respect to the fallen Pluto. In this talk, we'll examine the case for Planet 9, learn about the latest efforts to detect it and figure out if it is going to kill us all. Hint: no.
