The surface of the Sun shifts.
Text, Scientists are rethinking the physics of sunquakes - the Sun's equivalent of earthquakes - after re-analyzing data from NASA's Solar Dynamics Observatory. Credit NASA's Scientific Visualization Studio.
It's long been suspected that sunquakes are driven by magnetic forces or heating of the outer atmosphere, where flares occur.
However in this case, the acoustic source was found around 700 miles below the surface of the Sun.
So far, the connection between the submerged source of the waves and the solar flare is unknown.
