Sun Spots

Who knows what a sunspot is? One interesting fact about the sun are the sunspots. Sunspots are areas where the magnetic fields are about 2,500 times stronger than the earth's magnetic field. These fields are much higher than anywhere else on the sun. Because of the strength of the magnetic field the magnetic pressure attracts when the surrounding atmospheric pressure decreases. Which to me says that the Sun pulls all the other magnetic fields towards it. Sunspots only last for a few days then burn out.
A sunspot is the size of planet earth so think of how big the sun is.

  1. I hope you enjoyed researching this topic Te Aoturoa. The sun and stars have always been a fascinating learning area. Isn't it amazing how our tuupuna relied so much on the stars and heavens to guide them in everything they did?
    Great research blog.
