CFI Calgary Carl Sagan Day Celebration

Come celebrate Carl Sagan Day with us! CFI Calgary is proud to present Roland Dechesne, who is a Past President of the Royal Astronomical Society of Canada. Carl Sagan was best known for his contributions to the scientific research of extra terrestrial life. Roland will catch us up on the scientific advancements in the two decades since Carl Sagan’s death.

If popular culture is to believed, aliens regularly visit, and sometimes interact with Earthlings, perhaps over millennia. Using our knowledge of astronomy and physics, can we estimate how likely it would be that alien civilisations would have targeted our humble planet for visits? Roland Dechesne thinks he can, and perhaps the answers will surprise you.

Roland Dechesne bio: Roland is a Past President of the Calgary Centre of the Royal Astronomical Society of Canada and an amateur astronomer with over 35 years’ experience. He has been a popularizer of astronomy to the public for much of that time. His interests are astrophotography, meteorites and light pollution abatement. He ‘moonlights’ as an oil and gas geologist during the day.
