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!

RASC Mississauga: The Discovery of Gravitational Waves

Get an up-close and personal take on the Gravitational Waves discovery that has changed science for the better. Considered the most influential discovery of the century, gravitational wave GW150914 broke records in physics, astronomy, and interferometry - with still more to come. We will talk about what went into the Laser Interferometer Gravitational wave Observatory (LIGO) that discovered GW150914 from theoretical, engineering, and computer simulation viewpoints, and discuss the outlooks on the future of gravitational wave astronomy.

Autumnal Equinox

The earth's axis is perpendicular to its orbit with the North pole tipping away form the sun. In other words, the season is changing to Fall.

Hamilton Amateur Astronomers: 2 minutes and 18 seconds in the Shadow of the Moon

Imagine the air cools, the sky darkens, the birds stop singing and the stars come out at noon. For a lucky few who have been in the path of a total solar eclipse their imagination becomes reality as they experience one of nature’s most spectacular events.

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.

Runnymede Library: From Earth to Super-Earths and Beyond

It has been a little over 20 years that we know there are planets around other stars and 10 years that we know there are solid planets around other stars with the first super-Earth discovered: GJ876d. In the last few years, we have also learned that super-Earths and mini-Neptunes are the most common planet in the galaxy, improving our chances to find another habitable planet. To study these planets, we base our knowledge on what we have learned about the Earth and our planet neighbours, and test these ideas on these new and sometimes exotic planets. Dr.

Northern District Library: Science At The South Pole

Imagine viewing the leftover light from the Big Bang while stationed at the Amundsen-Scott South Pole Station in Antarctica. Professor Keith Vanderlinde from the University of Toronto has done just that. Professor Vanderlinde will talk about his work with the 10m South Pole Telescope, and the science that convinced him to undertake an eleven-month "winterover" position working on-location with the telescope. Presented as part of Science Literacy Week.
