    1. Sunspots are formed continuously due to that active magnetic field of the sun. To learn more about that go here; solar-center.stanford.edu/FAQ/Qspotsearth.html

    1. It is generally very hard to find star spots on stars smaller and/or further away than our sun. Therefore, it is easier to distinguish a star spot on a closer and more massive star. Doppler imaging is commonly used to detect and measure these star spots.

  3. Exactly how much bigger is a sunspot than earth? How much of the sun is made up of sunspots?

    1. Most spots range in size from about 1,500 km (932 miles) to around 50,000 km (31,068 miles) in diameter. Once in a while, huge sunspots the size of Jupiter show up on the Sun's surface.
      I found that at http://www.windows2universe.org/sun/atmosphere/sunspot_size.html

      As for how much of the sun sunspots take up, since they go away and are in an 11 year cycle, it is hard to find an accurate consistent number.

  4. Why is the sunspot cycle so long?

    1. The number of sunspots observed on the sun varies every year, but is on average an 11 year cycle. This 11 year cycle is likely due to the sheer size of the sun.

  5. Why can we not see sunspots with our eyes just by looking at the sun?
