Explore the night sky with astronomers from the Faculty of Science and Royal Astronomical Society of Canada. The Perseids meteor shower will be at its most spectacular, so let's gather to learn something and then enjoy the view! We will meet first at 7:30pm in the nearby Optometry building for a short lecture by the Department of Physics and Astronomy's Prof. Mike Hudson on

Cosmic Mirages: seeing dark matter with gravitational lenses

colour image of dark matterMost of the matter in the Universe is dark matter: an elusive particle that is completely invisible. But we can “see” this matter by studying how it distorts the light from galaxies in the distant Universe, a phenomenon called gravitational lensing. I will give a whirlwind tour of gravitational lensing’s “greatest hits” showing how it can be used as a tool to understand some of the most mysterious things in the Universe: from black holes to the “cosmic web” of dark matter that links galaxies together.

This is a family-friendly event, but if your kids will have trouble sitting through a lecture, you're welcome to join us on the Columbia Fields around 8:30pm for the stargazing portion of the evening.

Please note that if the skies are cloudy, the lecture will still take place on August 12th, but we will not gather on the fields for stargazing. Please register so that we can keep you updated:

Parking will be provided in Lot X, near the lecture venue, and in the OpenText lot on Frank Tompa Drive, north of Brubacher House. It is an easy walk between both parking lots, the lecture, and the fields. Please do not park in the small gravel lot adjacent to the field, as your car lights interfere with our stargazing.
