Sounds of the Stars
Arthur Eddington wrote a book called The Internal Constitution of the Stars
. He asked: "What... can pierce through the outer layers of a star and test the conditions within?"
Now we know the answer.
The sounds of the stars
We can use earthquakes to understand the inside of the earth. We can also learn about the insides of stars that pulsate.
They make very low sound waves. What if the waves moved a million times faster? We could hear the sounds of the stars!
Different stars would make different sounds. A star
like our own Sun is alpha Centauri (click to listen). A giant star like xi Hydrae sounds deeper. A tiny white dwarf star like GD 358 sounds higher. We can even make
from these sounds.
