Carl Sagan once said: “We are made of star stuff. We are a way for the cosmos to know itself”. What does that mean? How can we know about the physics and chemistry of celestial bodies just by looking at the sky?

This talk will show how astronomers decode the light coming from the sky to determine the chemical composition of stars, and how this gives us clues about our own origin and place in the Universe.

Stargazing (if clear)
