Sep 11, 2013 - Supernova Through the Ages - Jason Kezwer, UVic grad student

Supernovae are violent stellar explosions that can shine as bright as an entire galaxy. Spreading heavy elements fused in the stars into the cosmos, they are essential for life on Earth to exist. Over the last two millennia ancient astronomers have observed supernovae occurring in the Milky Way as the sudden appearance of new stars in the night (and often daytime) sky. Now, well into the telescope era, we are able to locate the remains of these destructive explosions and trace back their origins. Jason will describe this journey of discovery from the very first recorded supernova to the use of supernovae for measurements of the expanding Universe. The terrestrial effects of supernovae in our galaxy, both near and distant, will be discussed. Modern day research with a focus on supernovae in distant galaxies will also be explored.
