      Within the sun there are lots of chemical reactions going on which produce a lot of energy. It is this energy that is produced that makes the sun appear bright.

      The sun has many different reactions which are occurring, many of which produce energy. This energy can’t just disappear, so heat and light are produced. The amount of light we can see is only a small fraction of what the sun produces, as much of the radiated energy can’t be seen.

      There are some pretty powerful reactions going on in the sun such as fussion reactions where Hydrogen atoms collide at very fast speeds. This produces a lot of energy that is released as heat and light which makes the sun bright.

      YES the sun is so bright due to a process called nuclear fusion, which yields abundant energy. The fusion reaction, along with the sun’s enormous size, means it will continue to shine brightly billions of years into the future.
