Across San Francisco Bay from Lin, a group of scientists at Stanford University is looking at the sun's interior through a remarkable technique called helioseismology. (discovermagazine.com)
With helioseismology data, which track acoustic oscillations on the sun, researchers can follow the development of the jet stream thousands of kilometers below the sun's surface, potentially allowing for better forecasts of the timing of the solar cycle. (scientificamerican.com)
A third scientist used helioseismology to look at minima in acoustic oscillations that often correspond with sunspot minima. (scientificamerican.com)
