UofT Planetarium: Imagining the Size of the Universe

Showtimes: 7:00pm, 8:00pm, and 9:00pm How big is the universe? How can we seek to answer this question or understand the answer once we have it? Our universe is much bigger than we imagine it to be but, using analogies and visualizations, we can start to grasp its true dimensions. This planetarium show will journey through the different scales of the universe, starting with familiar objects like the moon and the Earth, and ending with the furthest reaches of the observable universe.

Dark Sky Star Party (GO for Wednesday)

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.

Speaker's Night: Dwarf Planet Revealed: New Horizons at Pluto

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!
