How Helioseismology Uses Sun Quakes to View the Core

TL;DR

Did you know that the Sun rings like a massive, glowing bell made of gas? This constant vibration allows scientists to look inside the star without ever touching its surface. While we cannot see through the thick, glowing plasma with light, we can listen to the sound waves that bounce around inside. Helioseismology is the study of these vibrations - It does not look for massive cracks or shifts like an earthquake on our planet. It tracks millions of tiny surface movements - these motions happen because sound waves travel from the hot center out to the surface and back again.
