How in the world could you possibly look inside a star? You could break out the scalpels and other tools of the surgical trade, but good luck getting within a few million kilometers of the surface before your skin melts off. The stars of our universe hide their secrets very well, but astronomers can outmatch their cleverness and have found ways to peer into their hearts using, of all things, sound waves.

"Sound waves in space" is a pretty confusing phrase, but don't worry, these sounds waves stay strictly within their stellar spheres. Every star is a dynamic, vibrating maelstrom of intense frenetic activity. On the inside you have the insanity of the nuclear core, forging new elements by the second at temperatures of millions of degrees. On the outside you have the vacuum of space itself, colder than cold at a temperature barely above absolutely zero.

Job - Body - Star - Heat - Inside

The job of the body of a star is to get all that heat from the inside to the outside, where it desperately wants to go. While throughout their lives stars exist in a state of equilibrium (they're not exploding in a supernova or collapsing into a black hole right now), any slight disturbance can persist as slight bumps and wiggles throughout the bulk of the star – and on its surface.

"Bumps and wiggles throughout the bulk" are also known as sound waves.

Ways - Stars - Patch - Layer - Bit

There are a few different ways that stars can start screaming. If a patch or entire layer of star-stuff just happens to be a little bit more dense than average, it can trap radiation underneath it, preventing it from escaping. This heats the layer abnormally, causing it to rise and expand, freeing the trapped heat and allowing the layer to cool back off and settle back to the way it started, resetting the...
