Detailed explanation-1: -The centremost region of the Sun is known as the core; this is the region where Hydrogen turns into Helium through the nuclear fusion reaction. With temperatures believed to be reaching more than 15 million degrees Celsius, the core is considered to be the hottest region of the Sun.
Detailed explanation-2: -The pressure is so high that when hydrogen atoms collide with enough force they create a new element-helium-in a process called nuclear fusion. The continual nuclear fusion, causes energy to build up and the sun’s core reaches temperatures of about 27 million degrees F (15 million degrees C).
Detailed explanation-3: -The sun’s corona It appears as white streamers or plumes of ionized gas that flow outward into space. Temperatures in the sun’s corona (opens in new tab) can get as high as 3.5 million degrees F (2 million degrees C).
