Sun’s core rotates 4 times faster than its surface

A team of global astronomers recently found that the Sun's core rotates near four times faster than its surface.

European Space Agency and NASA's Solar and Heliospheric Observatory (SOHO), together, helped the solar scientists find evidence of a type of seismic wave in the Sun.

These waves are known as g-modes and are low-frequency waves. These waves revealed that solar core is actually rotating four times faster than its surface.

The solar physicists used helioseismology to study the Sun's interior structure by tracking the way waves move on the star.

The scientists used over 16 years of data collected by SOHO's GOLF instrument (Global Oscillations at Low Frequencies). The study was published in the journal Astronomy and Astrophysics.

The Sun’s core is important because it may give a clue of how the Sun was formed.
