We may finally know what causes sunquakes. The cause of these strange rumbles within the sun has divided solar physicists for decades, but a new study has found that they may come from beams of high-energy electrons burrowing through the outer layers of the sun.
Sunquakes are waves in the sun’s photosphere – the surface from which its light shines – that ripple across the star like the waves from a pebble tossed in a lake. They are usually associated with …
