Starquakes are sudden and violent seismic disturbances that occur on the surface of stars. They are similar to earthquakes on Earth, but on a much larger and more powerful scale.
Starquakes are caused by the release of built-up energy within a star's interior. This energy is released when the star's magnetic field becomes twisted and strained, causing it to snap and send shockwaves through the star's surface.
Scientists study starquakes by observing the changes in a star's brightness and using specialized instruments, such as telescopes and seismographs, to detect the seismic waves produced by the quakes.
Starquakes are not dangerous to humans as they occur in outer space. However, they can have significant impacts on a star's structure and can affect the surrounding planets and objects in the star's system.
Yes, starquakes are a common occurrence and can happen on a regular basis in certain types of stars. However, they are not always observable from Earth and can vary in intensity and frequency depending on the star's age and activity level.
