About Chris Vaughan

My Story

Chris Vaughan – aka “AstroGeoGuy” – is an award-winning astronomer with a talent for explaining the cosmos to anyone – during his dynamic and fascinating presentations, or touring guests out under the stars. A professional Geophysicist and Astronomer (graduate of University of Toronto, 1982), his passion for education and public outreach won him the 2014 Bertram Topham Award for Observing and the 2013 and 2014 Andrew Elvins Awards for Promotion of Astronomy from the Royal Astronomical Society of Canada Toronto Centre. He is the author of a weekly astronomy news bulletin for non-astronomers, called Astronomy Skylights, which is received by subscribers worldwide. Since 1996, Chris has been visiting classrooms, hosting science-themed assemblies, running science clubs, and holding Star Parties for schools and private groups around the GTA. Chris has been an operator of the David Dunlap Observatory’s 74″ (1.88 m) Great Telescope, co-creator and regular presenter in their Skylab planetarium, and a speaker at their public programs. He is also a regular presenter of The Sky This Month at the monthly Recreational Astronomy Night meetings of the RASC Toronto Centre, and a member of the team at the club’s Carr Astronomical Observatory near Thornbury. He writes a column about Mobile Apps for astronomy for Space.com A Mineral Exploration Geophysicist since 1980, Chris has given classroom presentations on geology, rocks and minerals, mining, and archaeological age-dating. He has served two terms as president of the Canadian Exploration Geophysical Society (KEGS). An astronomy enthusiast since childhood, and a lifelong learner, Chris has been learning to speak, read, and write Mandarin.

Join astronomer Chris Vaughan for an evening guided tour inside the domes of the historic York University Observatory near Keele and Steeles in Toronto. See the telescopes, hear about the latest news and research and, if the skies are clear, view some fascinating objects. After the tour, we’ll retire to a local establishment for drinks, food, and casual astronomy talk with Chris.

Book astronomer Chris Vaughan for a night under the stars at your location. He’ll teach you how to find the North Star, share some myths and stories about the constellations, and explain how the sky’s motions produce our seasons, clocks, and calendars. You’ll gaze through state-of-the-art telescopes at planets such as Saturn, colourful double stars, spectacular and whimsical star clusters, and even you a galaxy or two. An unforgettable experience for all ages.
