Speaker for 12 May: Dr. Sun Kwok

stardust_b (2)At 7:30 PM, 12 May 2017, at the Sunshine Coast Art Centre, 5714 Medusa St., Sechelt, The Sunshine Coast Centre welcomes Dr. Sun Kwok, whose topic will be “Stardust: the cosmic seeds of life.” How did life originate on Earth?  For over 50 years, scientists believed that life was the result of chemistry involving simple molecules such as methane and ammonia cooking in a primordial soup.  Recent space observations have revealed that old stars are capable of making very complex organic compounds.  The stars then ejected the organics and spread them all over the Milky Way Galaxy.  There is evidence that these organic dust particles actually reached the early Solar System.  Through bombardments by comets and asteroids, the early Earth inherited significant amounts of star dust.  Was the development of life assisted by the arrival of these extraterrestrial materials?  In this talk, we describe discoveries in astronomy and solar system science over the last 10 years that resulted in a new perspective on the origin of life.

Prof. Sun Kwok’s research areas are astrochemistry and stellar evolution.  He is best known for his theory on the origin of planetary nebulae and the death of Sun-like stars.  His recent research has been on the topic of the synthesis of complex organic compounds in the late stages of stellar evolution.  He is the author of many books, including The Origin and Evolution of Planetary Nebulae (Cambridge, 2000), Cosmic Butterflies (Cambridge, 2001), Physics and Chemistry of the Interstellar Medium (University Science Books, 2007), Organic Matter in the Universe (Wiley, 2012), and Stardust: the cosmic seeds of life (Springer, 2013).  He has been a guest observer on many space missions, including the Hubble Space Telescope and the Infrared Space Observatory.

Prof. Kwok currently serves as President of IAU International Astronomical Union (IAU), Commission on Astrobiology.  Previously, he has served as the President of IAU Commission on Interstellar Matter (2012-2015) and chairman of IAU Planetary Nebulae Working Group (1994-2001).

Admission is free: donations gratefully accepted at the door.
