Sound Wave Oscillations of the Sun

Sound Wave Oscillations of the SunThis computer representation depicts one of nearly ten million modes of sound wave oscillations of the Sun, showing receding regions in red tones, and approaching regions in blue. Using the NSF-funded Global Oscillation Network Group (GONG) to measure these oscillations, astronomers are learning about the internal structure and dynamics of our nearest star.
