Abstract
The sky above Quebec’s Jarnac Pond was inky, the night silent except for the occasional croak of a frog and the hoot of an owl. I could see more stars than I could count, and the Milky Way arched right overhead. I was 14, and for the past 2 years I’d been increasingly drawn to astronomy. “You are going to sit on the dock all night long? Until dawn?” My astonished grandparents couldn’t believe my plan. On that lazy afternoon of August 12, we were watching clouds pass by and talking about the very bright meteor we had seen the previous evening. I had read in a book how, each August 12, the Earth’s orbit intersects the orbit of a comet called Swift-Tuttle, and over a very long time, dust from that comet had spread all along the orbit, resulting in the Perseid meteor shower.
