Core
The core of the Sun is considered to extend from the center to about 0.2 to 0.25 solar radius.
Radiative Zone
Energy travels through the radiation zone in the form of electromagnetic radiation as photons.
Convective Zone
A region of turbulent plasma between a star's core and its visible photosphere at the surface, through which energy is transferred by convection.
Photosphere
The luminous envelope of a star from which its light and heat radiate.
Chromosphere
A reddish gaseous layer immediately above the photosphere of the sun or another star
Corona
The rarefied gaseous envelope of the sun and other stars.
Sunspots
A spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundings.
Prominence
A large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape
Flare
A sudden eruption of magnetic energy released on or near the surface of the sun.
Aurora
The result of charged particles colliding, creating bright lights in the sky.
