Stellar Explosion and Exoplanets: Alex Filippenko at the Lair
“Some stars literally explode in a titanic act of self-destruction at the end of their lives, becoming some million or billion times as powerful as the sun,” Filippenko explains to Lair of the Golden Bear campers. “Exploding stars are not just spectacular to look at, but they’re important for our very existence, because during its life a star generates energy by fusing light elements into heavy elements. Right now, the sun is fusing hydrogen to helium; later it will fuse helium to carbon and oxygen. If stars never exploded, the heavy elements would be forever trapped in their cores and thus not available as raw material for the production of new stars and planets.”
