Astronomy Talk: The Wonder of Comet ISON, A Relic From the Beginning of the Solar System

Dr. Carey Lisse, head of NASA’s Comet ISON Observation Campaign, will present a timely talk on how and when comets were formed, and where they come from. Also a Senior Research Scientist with Johns Hopkins University Applied Physics Laboratory, Lisse will relate how comets may have helped start life on the Earth, and also how they may have ended it for millions of creatures at least 4 times in the past. He’ll also give a bit of the history of comet observing by mankind, and explain how Comet 2012 S1 (ISON) fits into this picture of comets as relics from the beginning of our solar system.
