Western Space in collaboration with the Department of Physics and Astronomy and Royal Astronomical Society of Canada - London Centre will be hosting a special event on Asteroid Day (June 30th). Asteroid Day is a global awareness campaign where people from around the world come together to learn about asteroids and what we can do to protect our planet, families, communities, and future generations from future asteroid impacts. Asteroid Day is held each year on June 30, the anniversary of the largest impact in recent history, the 1908 Tunguska event in Siberia.

Public Talks by Asteroid Experts

Dr. Paul Wiegert 

Talk Title: "Asteroids: deadly danger or imminent catastrophe? (or maybe neither!)"

Talk Blurb: The talk will try to answer the questions: What are asteroids exactly? How do astronomers search for them? and what danger do they pose?

Speaker Bio: Dr. Paul Wiegert is a Professor in the Department of Physics and Astronomy at Western University. His research interests include asteroids, comets and planetary dynamics. 
Dr. Mark Tovey

Talk Title: "W.G. Colgrove and the Dresden Meteorite"

Talk Blurb: W.G. Colgrove was Cronyn Observatory's astronomical model-maker extraordinaire, and was awarded the highest honour of the Royal Astronomical Society of Canada, the Chant Medal. What is possibly less well remembered about Colgrove is that he observed the famous Dresden meteorite when it was still a meteor streaking through the sky. Learn a little more about Colgrove's role in the Dresden meteorite story, how the Dresden meteorite came to Western, and the story behind the “new” Dresden meteorite (in 3D printed form!).
Speaker Bio: Dr. Mark Tovey is an Adjunct Research Professor in the Department of History at Western University and member of the Royal Astronomical Society of Canada.
