"Scientists have long known that the atmosphere of the Sun oscillates. In the same way seismologists use earthquakes to model the interior of the Earth, helioseismologists use vibrations observed on the Sun to probe deeper into our star. Oscillations of about 25 other stars have also been studied in the emerging field of asteroseismology. Now, thanks to the Kepler space telescope, a team led by Bill Chaplin, at the University of Birmingham, UK, has increased this figure significantly."
