Prof. Jaymie Matthews, of the Department of Physics and Astronomy at the University of British Columbia ruled out several possibilities of what the object could be.
“A comet that bright, that close to the Sun, visible in the twilight sky, would have been spotted by professional and amateur astronomers long before last night,” he wrote in an email to CTVWinnipeg from Paris. “And it would have been visible to people across North America last night, and still tonight.”
Chris Rutkowski from the Winnipeg-based Ufology Research Institute said his best bet would be a plane. My best bet? A wicked new promotion mechanism for the next season of Smallville!
