Canadian Comet Sleuth David Levy: Webinar 4PM Thursday July 30th

The Canadian Comet Sleuth David Levy, author and comet hunter
Comet NEOWISE has been the sensation of our July skies, the first naked-eye comet for the Northern Hemisphere in ages. David Levy knows all about comets that snag the spotlight. Comet Shoemaker-Levy 9, which broke apart in July 1992 and collided with Jupiter in July 1994, garnered the “Canadian comet sleuth” media attention around the world, including the headline on the very first cover of SkyNews 25 years ago.
Join The Royal Astronomical Society of Canada’s Jenna Hinds and SkyNews’ Allendria Brunjes as they sit down with Levy in the next Speaker Series, at 7 p.m. on Thursday, July 30.
Levy has discovered 22 comets, given innumerable lectures and written countless articles and more than 30 books — including an autobiography, A Nightwatchman’s Journey. There’s an asteroid named in his honour, and his awards include the Chant Medal of The Royal Astronomical Society of Canada.
