Helioseismology: the sound of the Sun

Observations of resonant phenomena on the Sun are now being made that have their origins not only in the interior, but also in structures in the tenuous solar atmosphere. The challenge for solar researchers is to reconcile the flood of observations and theory from these varied scales and locations to further improve our understanding of the Sun. Here, we took at some of the exciting challenges facing researchers delving into the seismology of the Sun.
