City Star Party (GO for Monday)

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!

UofT AstroTour: On Pulsars: Ultra-Dense Material Spinning Dizzyingly Fast

Pulsars are magnetized spinning neutron stars that emit a beam of radiation. Since the first pulsar was discovered in 1967, thousands have been detected since, and they continue to be one of the most interesting objects in the sky. In this talk, Nikhil Mahajan will go over the history of pulsar astronomy, the reasons why we care about pulsars, and of course, what pulsars really are. Hopefully, this talk will leave you with an understanding of what current pulsar research is all about, and what it may lead to in the future.

Dark Sky Star Party (NO GO)

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.
