"How to Blow Up a Star"

"How to Blow Up a Star" with Cheyenne Polius

Summary:

The biggest and brightest stars in our universe live fast and die young, ending their lives in spectacular explosions bright enough to outshine entire galaxies. Every second, a star explodes somewhere in the universe and this talk gives you a cosmic "tutorial" on exactly how we get these magnificent explosions. Astrophysicist Cheyenne Polius takes you through the fascinating life of stars: how they form, the nuclear reactions that sustain them, and eventually, what causes their dramatic death. Join us as we explore the science behind stellar life (and death) and discover what the explosive end of stars can teach us about our own origins.

What happens at Pints of Knowledge?

At each Pints of Knowledge event, you’ll hear engaging talks (approx. 40 minutes) from expert speakers on fascinating topics — followed by an audience Q&A (approx. 20 minutes). The vibe is informal and social, set in a pub where you can grab a drink, meet interesting people, and enjoy big ideas in a relaxed setting.
