Sun's Surface is Thinning Sound Waves Reveal

Stellar Sound coming from the Sun has indicated that the outer layer has gotten weaker the past years, this according to new studies from Great Britain.

Sound waves released from the Sun, like musical instruments, informs us the way these waves are shaped.

Simply by listening to the frequencies the sun emits, scientists can study the sun's oscillation telling them something about the object producing the sound,

The waves also gives them information about the inside of the sun and allows the scientists to chart changes in its life.

This process has allowed scientists from the Birmingham University to determine the outermost layer is growing thinner.

Wave Tracking

The sun, like Earth, is made up of layers, the outermost one, being a few hundred kilometers wide, is made up of Plasma, so NASA claims.

This plasma is some hot mix of separated ions and electrons which are charged and therefore create natural magnetic fields.

They say that the movement of the plasma creates these sound waves who travel in and outwards. This process will tell the science community a lot about the inside of the star, as well as the workings of the magnetic field.

Conclusion

By studying previous solar cycles scientist have been able to confirm that the solar layer has definitively thinned, data suggests it has not been this thin for around a century.

This concludes the scientist to believe that this is thinning of the layer is not part of the 11-year cycle of the sun's activity.
