Asteroseismology

Asteroseismology is a way of learning about stars by looking at the sounds they make. Just like humans and animals make sound, stars make sound too! The sound stars make is called "asteroseismic waves" and by measuring these waves, scientists can learn things like a star's temperature, size, and age. It's like doctors listening to your heart beat to learn how healthy you are!
