Core

"The central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light."

Radiative Zone

"The section of the solar interior between the innermost core and the outer convective zone. In the radiative zone, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation."

Convective Zone

"It extends from a depth of 200,000 km up to the visible surface of the Sun. Energy is transported by convection in this region. The surface of the convection zone is where light (photons) is created."

Photosphere

"This is considered the surface of the sun. You can also find sunspots here, which are dark spots that appear on the surface on the surface of the sun. They appear darker because they are cooler than the surround areas"

Chromosphere

"The chromosphere is the layer above the photosphere. It appears as a red glow around the sun and is almost transparent."

Corona

"An aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph."

Solar Prominence

"Huge arches (loops) of glowing gas that extend outward from the sun’s surface"

Solar Flare

"Explosions occurring on the sun. Solar flares often occur near sunspots"

Aurora

"a natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole"
