Imagine that you are traveling in a spaceship to the center of the Sun. What would you experience and see in each of the Sun's regions?

First of all you would die. Do not try this at home but back to the question. There are six parts of the sun. From the outside to the inside: corona, chromoshpere, photosphere, convective zone, radiative zone, and the core. Then use the dictionary or reliable sources such as Wikipedia to find out what they do. Good luck.
