UofT AstroTour: World on Fire: Glimpses of the birth of the universe

By listening to the cold, dim hiss of the universe, we can learn about its fiery beginning. Prof. Renée Hlozek's talk will focus on how cosmologists use microwave instruments to measure this birth-light. She’ll describe the telescope she uses, high up in the Atacama Desert of Chile, and what we learn about what the universe contains, how it started and ultimately how it is going to end.

Dark Sky Star Party (GO for Monday)

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.
