Starquake iPhone App - now available on iTunes.

The app is called Starquake. NASA's satellites allow us to see full-motion video the Sun in 3D and at various wavelengths (pretty colors!). Helioseismology allows us to hear what the Sun sounds like. You've probably heard that there is no sound in Space. But there is sound on the Sun, just as there is sound on Earth - only much more violent. I've integrated it into this beauty of an app.

(for the curious, Sol is not the only star we can 'hear'. We've 'heard' the heartbeat of several stars outside of our system.)
