Imagine that a small, bright object appeared in the sky, moved along with a nearby constellation, and then disappeared a year later. Scientists in China, Persia, Europe, and Central America observed the event. Where did this phenomenon most likely occur? How do you know?

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
