They move with the Sun as the Sun rotates. However, these sunspots are the site of strong magnetic fields. Also, if yo u look closely, you can see granulation on the surface of the Sun. This happens because of the tremendous heat coming from the solar core. The bubbles of hot material welling up from below are seen at the photosphere, as slightly brighter regions.
Darker regions occur where cooler plasma is sinking to the interior.
There are currently 112 elements in the periodic table. Nuclear fusion is the process in which 2 atomic nuclei combine to form a heavier element. This type of reaction releases huge amounts of energy. The most common fusion reaction occurs on the Sun in which hydrogen atoms fuse to form helium. If scientists can figure out a safe and efficient way to carry out fusion reactions Earth, this would provide us a sustainable and clean source of energy for hundreds of years to come.
