sunquake

Star's surface shaking

A sunquake is a seismic event on the sun's surface, analogous to an earthquake but occurring in solar plasma rather than rock.

Sunquakes produce ripples that radiate outward from the point of origin, typically triggered by solar flares or coronal mass ejections.

The phenomenon was first observed in 1998 and helps scientists study the sun's interior structure.
